I was very critical of Kemba on the game thread, but I'm not a Kemba hater by any means. I'm very excited to have Kemba here. My main point was Rose should have been running the offense at the end of the game, and Kemba playing point down the stretch was the key reason we ended up in overtime.
That said I think there's a clear delineation here that was made apparent by last night's game.
First off, the way I see it, Kemba and Rose are not necessarily the same types of players. Kemba is the definition of the combo guard scorer. Derek Rose is a trained point guard who has been mostly a score first guy, but has all the requisite PG skills. Rose last year proved to be a smart, low turnover ball handler and was a super smart player that effectively picked his spots to score efficiently. Kemba is an explosive offensive player who can break down a D and get hot and shoot the lights out. He isn't a steady hand at PG to run a tight, efficient offense, but he can be a playmaker and rack up lobs/assists with his penetration. Last night Rose didn't shoot well, but in the 2nd OT when he played, the O was more under control and he made a huge shot with the game on the line. Kemba playing with the lead, was foiled by the trap, couldn't get the offense started and gave the game away with a couple of turnovers and was caught in a bad place on D.
So based on the above, the way I see it, when you have a lead at the end of a ball game, Rose is the closer. You need a steady hand to take care of the ball, milk the clock, beat the press and run the offense efficiently, go Rose. You need someone to hit a clutch basket when the defense is keying in, Rose can figure it out.
If you're down 10 pts in the 4th quarter, Rose is a great scorer too, but Kemba can be the type of explosive offensive player to bring you back in the game.
And there are some tight games where you may want both guys - Rose's steady hand and Kemba's shotmaking down the stretch.
I'm fine with Kemba starting games - honestly the first 3 quarters I'm not sure it matters, but its at the end of the game that I want to make sure when the situation dictates, we have a true PG out there.
Over the course of the year Kemba is going to go off for 30+ many times, will be a huge boon as a 2nd scorer and give us some explosion at the start of the games we lacked w/ Payton etc. Having he and Rose out there will preserve each other. But I think last night, he was thrown in a situation that wasn't maximizing his skill and we had the right guy on the bench.
Also, next time I'd like to not see him high fiving a bunch of his old teammates all game...but that's another story that's not relevant to the above!
