No. He is not good.
If he gives us more than BBD I am for it.
That's my perspective. Shelden has terrible hands. However, I'm happy with everything else I've seen. If BBD can't produce, it doesn't hurt to give Shelden some run, sort of like how the team handled the BBD/Powe situation. Doc should go with who is playing better.
Williams has also played significantly worse defensively than Davis has. Yes, Williams is a better rebounder, but he can't defend inside, or out, is a horrendous offensive player, and fumbles away 2-3 balls a game. He is a net negative, while Davis is a net positive (despite being an idiot).
Another example of overstated misleading information to try and back up a point. You'd think a guy that fumbled away 2-3 balls per game would have more than .79 turnovers per game. Those would be turnovers and then his average would be somewhere in the 2.5 per game level.
As far as horrendous offensive player, the guy averaged 4 pts on 49% shooting from the floor in his 12 min. Seems to me since he is .60 better from the floor than BBD (.43) I would also argue the stats seem to contradict your statement. You can't shoot a better % from the floor, and basically the same FT% and be considered a WORSE offensive player.
So what we have here is a guy who USED to play better defense than Shelden, NEVER was a better rebounder, has a better FG %, an equal FT%, didn't break his hand on his friends face right before the season started when he should have been focusing on the season, and isn't more worried about his nickname than his big drop in level of play, that you think is a much better player than Shelden. Sounds a little like you just dislike the guy vs. owning up to the fact that HE is the one that should be out there on the floor. Championship teams play the people who DESERVE to be on the floor, not people who used to produce. Maybe that's why we really aren't in the running at this point.
