I think Stu is fine in small doses. Bad play-by-play partners these recent years have amplified his role and he has trouble filling that spotlight. Back when Chick was at the mic Stu stuck to his knitting and was ok. He has improved a lot since then but the demands on him have outpaced his growth.
He does, btw, eventually let go of the repetitive phrases. He used to say something about 'moving your feet' about 20 times per game and he has backed off that one.
Stu has some very insightful comments about how bigs should play. His recent mention of 'jumping even when you can't get the rebound' to avoid the other player coming down on you was an example. Unfortunately he seems to think we don't know that shoving with your hands draws more fouls than a hip check
If he had a stronger partner he wouldn't feel the need to reach so much - he could say the insightful stuff and omit the dead obvious crud.
Lately Stu has been talking as if its his job to coach the other team's bigs. Tips on how those opponents can play better and 'what they need to do.' Perhaps he has to be careful giving tips on the Laker bigs because it will get back to them and weird the relationship. Either way, he has been coming across as if we want to hear what the bad guys 'need to do' to beat us.
Anyway, I'll keep him if only for the occasional personal stories related to his old days with Chick. I used to go to the forum and stop by to talk to Chick after the game (he sat in a perch halfway up the stands in the middle of the fans so you could do that then). Anybody who can tell chick stories can sit in the second chair on Laker broadcasts as far as I'm concerned.
