To improve the defense and rebounding of the team, but diminish the offense in the process.
I think you mean not diminish the offense.
Below is a comparison of the combined production of Kornet/Vonleh/Griffin and Kabengele
VS Rob's last year numbers pro-rated to 21.9 mpg
MPG FG FGA FG% 3PM 3PA 3P% 2P_ 2PA 2P%_ FTM FTA FT% ORB DRB TRB AST STL BLK TOV PF PTS
Combined/Game 21.9 2.5 4.3 0.589 0.3 0.9 0.368 2.2 3.5 0.645 1.0 1.0 0.913 2.3 3.7 6.0 1.2 0.3 1.1 1.0 3.4 6.4
RWIII 21.9 mpg 21.9 3.3 4.4 0.736 0.0 0.0 3.3 4.4 0.738 0.8 1.1 0.722 2.9 4.2 7.1 1.5 0.7 1.6 0.7 1.6 7.4
It is hard to follow the numbers but I think the bottom line or your point is that Kornet/Vonleh/Griffin are giving us about 6/6 while RWill gave us about 7/7. You adjusted this per 21.9 minutes though which distorts the absolute value of the stats some.
RWill is a starting level center and if he is back at full or near full strength, he is going to give us quite a bit more in his 20 minutes then we are ever going to get from Kornet et al if they were to play for 20 min. It will also allow Grant to play off the bench where he is much better.
The question is of course whether or not it is expected that RWill will be back at full or near full strength, and if so, for how long. There is just no way to know how his knee is going to hold up. If it does hold up, we have seen what he can do and what he brings to the team and it is a lot more than what we have been getting out of the committee of back ups.
Its in response to "What are you expecting / hoping for with Rob Williams?"
If Rob can play like last year, but 22 mpg, I'm happy.
Its already an upgrade. The numbers don't suggest a drop off in offense, and they do suggest an upgrade on defense.
Rob, won't play every game, but he will probably play more than 22 mpg when he's available.
Anything over the 21.9 mpg is good. Al plays less, Grant comes off the bench, Vonleh is relegated to garbage time.
