Trivia time: Only two players have ever won the Rookie of the Year award in a unanimous vote? Who were they?

A hint: Both unanimous winners were big men, but neither was named Shaquille O'Neal. Shaq pulled in 98 percent of the vote in 1992-93, outpolling Alonzo Mourning 96-2. Another hint: Both played their rookie seasons in Texas.

That question has become relevant again as Chris Paul of the New Orleans/Oklahoma City Hornets has dominated the competition.

In this season's Rookie of the Year race, the only compelling question remaining is: Who's No. 2?

"Chris Paul has been the guy for months now, but people want to see who's that second or third guy," said Toronto's Charlie Villanueva, who just might be that runner-up. "I think Chris Paul, he deserves it. But I think I have a shot at being runner-up if I keep doing what I've been doing."

The NBA expects to mail out more than 120 ballots to writers and broadcasters for Rookie of the Year voting, and Paul stands a better-than-decent chance of becoming the third unanimous winner. The others were David Robinson of San Antonio in 1989-90 (92 of 92 votes) and Ralph Sampson of Houston in 1983-84 (76 of 76 votes).

Paul leads all rookies in points, assists, steals and minutes, with commanding leads in those first three categories. He has led the surprising Hornets into the thick of the Western Conference playoff race as the new floor general for a relocated franchise coming off an abysmal 18-64 season. In other words, case closed as far as who deserves everyone's Rookie of the Year vote.

With that out of the way, let's look at some key questions about the rest of the rookie class:

So who is No. 2?
Since moving into the starting lineup Feb. 3, Villanueva has averaged 15.8 points and 7.9 rebounds with 48 3-pointers -- numbers many believed would be unlikely when the Raptors made the University of Connecticut forward the seventh overall pick of last June's draft.

The pick was widely criticized since the Raptors already had a top-tier power forward in Chris Bosh, but Toronto has turned Villanueva into an oversized small forward who they believe has the quickness and agility to defend opposing 3s.

Villanueva honed his shooting skills by putting up more than 1,000 3-pointers per day in the weeks leading up to the draft, a pace he hasn't been able to keep up due to the rigors of the NBA season, although he's trying. "A couple hundred a day," Villanueva said.

After attempting only a dozen 3-pointers (making six) during his final season at Connecticut, Villanueva is 48-for-141 (34 percent) through the Raptors' first 59 games.

Only five rookies -- all of them guards -- have made more 3s than Villanueva.

"When we brought Charlie in for his workouts, we knew he could shoot the basketball," Raptors coach Sam Mitchell said. "I just laugh at people, because this kid would have been a late first-round pick out of high school, and for people to think he couldn't be a high first-round pick after going through a program like Connecticut, winning a national championship and playing under a coach like Jim Calhoun, maybe I'm just stupid, but I thought all those things were positives."

Villanueva rated Channing Frye and Andrew Bogut his top competition in the race to be runner-up to Paul.

Frye has not been the consistent performer he was earlier in the season for the New York Knicks, although that's not entirely his fault. With his minutes and role fluctuating wildly under the whimsical leadership of Larry Brown, Frye has failed to score in double figures in 13 of his last 25 games after doing it in 23 of his previous 25.

Bogut, the No. 1 overall pick, hasn't had a 20-point game since Dec. 10, his production dropping significantly over the past five weeks as the Bucks have lost 10 of 16.

What about the actual No. 2 guy?
Atlanta's Marvin Williams, the No. 2 pick, has shown recent signs of blossoming (14 points, 10 rebounds, three steals Tuesday vs. Golden State). Plenty of personnel people and analysts still insist the 19-year-old is a can't-miss superstud in the making, but Williams' long-term role with the Hawks will undoubtedly be affected by Atlanta's decision over the upcoming summer whether to keep Al Harrington after he becomes an unrestricted free agent.

How's the rest of the lottery looking?
In Utah, it'll be a long time before the Jazz stop second-guessing their decision to give three No. 1s to Portland for the right to pass over Paul in favor of Deron Williams, despite Williams' double-figure scoring output in Utah's last eight games.

Paul was the No. 4 pick, right before Raymond Felton (Charlotte) and Martell Webster were chosen ahead of Villanueva and Frye. Felton's role has increased significantly, and he averaged nearly 16.0 points per game last month for the Bobcats, while Webster has made nine starts but is averaging less than 5.0 points per game for the Blazers.

Picks 9 and 10 have had little impact, Andrew Bynum (No. 10) providing less to the Lakers than Diogu (No. 9) has to the Warriors. Pick No.11 was Fran Vasquez, who shocked the Magic by choosing to play in Spain, and No. 12 was 18-year-old Russian teenager Yaroslav Korolev, who has reached double figures in minutes only three times while scoring 25 points in 22 games for the Clippers.

No. 13 Sean May hasn't played for the Bobcats since mid-December after having cartilage cleaned out of his knee, but could return this month. No. 14 Rashad McCants has become a 20-minutes per night contributor for Minnesota over the last month.

What about the guys after the lottery?
Of the players selected ninth through 30th, only Danny Granger of Indiana (No. 17), Francisco Garcia of Sacramento (No. 23), Luther Head of Houston (No. 24) are averaging 20 minutes or more of playing time, though Hakim Warrick (No. 19, Memphis) is moving toward that type of a role and Jarrett Jack (No. 22 Portland) has been a steady backup point guard in Portland.

Nate Robinson (No. 21, New York) won the dunk contest at All-Star Weekend but has been buried on Larry Brown's inactive list ever since. Antoine Wright (No. 15, New Jersey), Joey Graham (No. 16, Toronto), Julius Hodge (No. 20, Denver), Jason Maxiell (No. 26, Detroit), Linas Kleiza (No. 27, Denver), Wayne Simien (No. 29 Miami) and David Lee (No. 30, New York) have done next to nothing, though Graham, Kleiza and Lee have had some moments.

Ian Mahinmi, selected 28th by San Antonio, is averaging nearly 11 points and shooting almost 60 percent for Le Havre of the Franch A League.

Who's the international rookie of the year?
Among the older international rookies, 30-year-old Sarunas Jasikevicius of Indiana has made 15 starts and logged 23 minutes per night, although his shooting (.417 overall, .377 from 3-point range) has not been as good as the Pacers had hoped. Jose Calderon, 24, has been mediocre as the backup to Mike James in Toronto, while Fabricio Oberto, nearly 31, had been a nonfactor as the third-string center behind Nazr Mohammed and Rasho Nesterovic in San Antonio.

Johan Petro (No. 25) has been in and out of the starting lineup at center for Seattle, reaching double figures in rebounds only three times in 49 games.

Which second-rounders are making the best case to have been taken earlier?
For much of the season, the best-looking second-round pick was the player who went at the top of that round, Salim Stoudemire of Atlanta. His 76 3-pointers are second among all rookies behind Head's 83, and Stoudemire's 9.6 scoring average is sixth.

But take a look at what Boston's Ryan Gomes has been doing over the past nine games, including back-to-back outputs of 27 points and nine rebounds Tuesday against Washington and 29 points and 11 rebounds the next night against Philadelphia. If he keeps up that pace, Gomes might just pull a vote or two away from Paul.

Who's the Rookie Dud of the Year?
The lowest-impact rookie of them all (aside from Orlando's Fran Vazquez, who decided to remain in Spain after being chosen 11th overall)? It was Deng Gai of Fairfield, who failed to record a single statistic in five minutes of playing time in two early-season appearances for Philadelphia before the Sixers cut him. The runner-up to Gai is Cleveland's Martynas Andiuskevicius, who has not yet scored (0-for-1 from the field with four rebounds, two steals and a personal foul) in six appearances for the Cavs.
