Agreed re the fouls, that is a valid point. However, Kendrick Perkins was incredibly foul prone for the first "four" years of his career. ( I believe he ranked in the top 5 in the NBA in fouls per minute over theose four years and perhpas even was #1 in fouls per minute at times). Should we not have played him and continued to "bring him along"? If we had persueed that path with kendrick and said well, he fouls too much, let's not play him...would he have progressed enough to be the starting center of the NBA champions.
I'm not saying we need to play him 30 minutes a night, all I'm saying is 5-10 minutes a night "when he is doing Ok" and continue to bring him along...if he struggles right away, yank him...just like we did for "four years" with "Kendrick Perkins". kendrick was also incredibly frustrating with his offense and putting the ball on the floor...but with time and game time over four years he has slowly learned not to do those things as much.
I think it's hard not to say that the good things he did on the floor last night, far, far, far outweighed the two fouls which were bad and were, as you correctly stated, due to being out of position, badly.
However, he was in great position on more plays, like when he blocked two shots on one trip or did some nice foul line shows and quick lane drops on others.
You can help the pace of player's progress by rewarding them after good efforts...I think he should get another 5-10 minute opp based on a very good, solid effort last night.
