Rookies are going to look clueless. He made plenty of mistakes. I remember yelling, "Don't jump", "Do not reach in- you didn't rotate in time", and similar things at Bender (Well, at my TV) many times. Somebody on this board years ago said to watch a particular player. Don't watch the game- just keep an eye on this one guy. I think it was AZSteven talking about Scola. I ended up doing just that, and within ten minutes, I understood exactly what he was talking about. I did this again, and I saw outstanding foot work, excellent defensive instincts, and a solid understanding of the game. I also saw somebody who knew what he needed to do, but was frequently just a couple of moment too late. That's inexperience. He is 18 years old.
I do agree with you that Chriss was much better than anyone expected. He has a good feel for the game, and very good instincts. I would propose that Chriss exceeding our expectations may have affected the way we look at Bender's season. Bender didn't quite look the same after his injury, which is completely normal, so we may be experiencing some recency-bias. I think Bender looks like a high-potential kid should look in the first NBA season. Let's see how he does next year. We should see some progress.
