Chris Webber is being benched in the 4th Quarter in favor of Steven Hunter and Samuel Dalembert. It may just be a flukey start by Webber, but the day KT is better has already come.
The main problem with the three main Sixer bigs as I see it is that not one of them can offer the full compliment of skills which Mo Cheeks is looking for down the stretch of games. Dalembert can guard the rim and rebound pretty well, but he picks up silly fouls, takes ill-advised shots on offense, and basically only scores when handed the ball at the rim. Hunter is a little bit more in control offensively, but not quite as good defensively, as Dalembert. CWebb can no longer defend, especially when opponents force him to guard a high pick and roll, and his rebounding has become a stationary pursuit. Couple that with the fact that he's not shooting the ball well (even by his low Philly standards of the past one and one-half seasons).
So, Cheeks generally opts to go small from what I have observed, running Korver at the PF for his shooting on offense (which he has been doing quite well this year) and his hustle on defense. With most other teams going without a traditional PF/C combo, the Sixers haven't been terribly hurt by this lineup.
The frustrating (and predictable) part of this scenario is that CWebb keeps talking about it to the media...he made mention of not being willing to accept this reduced role personally because it would signify that he was giving in to being that player. Fine. Shows (from a glass is half full perspective) that he at least has some pride left.
But now he keeps talking about it, and each time he says something else, it's a little more slanted to the complaint side of the equation, and he's not exactly tearing it up on the floor to justify staying in the game, either. I do recall that he had a pretty solid 4th quarter against the Raptors earlier this year, even making a defensive play on Bosh with the clock running down at the end of the game in a tie game...unfortunately, Bosh recovered the ball and drained a three pointer to give the Raptors the win.
It appears to me that Mo Cheeks has determined that he doesn't need more offense than AI and a cast of other mid-level NBA offensive talents to win games, so he's going without CWebb down the stretch. And considering that at this point CWebb is only playing like a mid-level offensive talent and a low-level defensive talent, it doesn't surprise me that this strategy is being taken (although it does pain me to watch). I wonder why the Sixers didn't just get CWebb off their cap last year ala Dallas and Michael Finley.
EDIT: OK, I know CWebb wouldn't have come off the cap, but at the very least his salary wouldn't have counted for tax purposes.
