I thought it might be interesting to track the jump shooting stats of a couple of other players that have been mentioned in this thread. First off is Eric Snow and his vaunted jump shot. Here are Snow's stats for the 02/03 season with Philly:

Eric Snow (02/03 season)

.403 eFG% on jumpers (65% of all FGAs)

2 point jumpers: 2.39 - 5.91 (40.4%)
3 point jumpers: 0.1 - 0.4 (21.9%)

Turns out he's not very hot stuff. Snow barely attempts any 3s, so the adjustment for his FG% on 2 point jumpers is always very close to his overall eFG% on jumpers. That means you can look up his jump shooting stats on 82games.com and get a good feel for his accuracy on 2 point jumpers just by looking at his overall eFG% on jumpers. It's not very good-- he's consistently at or below .400 eFG% on jump shots. (The 82games.com stats don't go farther back than 02/03, so it might be that Snow was a better midrange jump shooter earlier on, e.g. when the Sixers went to the Finals. A quick scan of his FG%s from espn.com makes this seem unlikely, though.)

Next up, Richard Hamilton. This is a bit of a shocker.

Richard Hamilton (04/05)

.406 eFG% on jumpers (74% of all FGAs)

2 point jumpers: 3.85 - 9.72 (39.6%)
3 point jumpers: 0.5 - 1.6 (30.5%)

Hamilton's jump shooting accuracy isn't as good as you'd expect from his reputation. It very well could be that his percentages are lower because he's always running off screens and being heavily defended and so on, which makes his shots more difficult than normal. Still, the end result efficiency is surprisingly low. (Hamilton is another guy who doesn't shoot a lot of 3s, so his eFG% on jumpers is also a very good indication of how well he shoots the 2 point jumpers. From 02/03 until last season, his eFG% on jumpers have been .414, .408, and .406.)

Szczerbiak and Houston were mentioned in this thread as masters of the art of the midrange jump shot. The numbers bear that out emphatically. Houston's red hot 02/03 season might be instructive in reforming the bad press Houston tends to get. Maybe he was 'only' a jump shooter, but damn, what a jump shooter he was! Allan got just as much coverage on his jump shot as Hamilton gets these days, and he attempted a whopping 93% of his FGAs on jumpers, so the defense always knew what was coming. Nonetheless, Houston's accuracy simply puts Hamilton's to shame. Szczerbiak isn't chopped liver himself, but I get the impression that he shoots most of his jumpers on kick outs, whereas Houston had to create a large portion of his jump shots himself.

Wally Szczerbiak (02/03 season)

.508 eFG% (83% of all FGAs)

2 point jump shots: 4.10 - 8.82 (46.5%)
3 point jump shots: 1.2 - 2.8 (42.1%)

Allan Houston (02/03 season)

.515 eFG% (93% of all FGAs)

2 point jump shots: 5.27 - 11.15 (47.3%)
3 point jump shots: 2.5 - 5.5 (39.6%)

Eric Snow's contract is UGLY. Jerry West signed Mighty Mouse, traded for Bobby Jackson & Burks & Lopez to go along with Troy Bell. And let Watson walk. Thats how high Jerry West is on Watson.
