I am wondering if most peoples expectations for both Donnal and Chatman were raised based on all the chatter. You know the whole Donnal looks great in practice and Chatman could be the next Jalen Rose. Both of which were obviously not the case when it came to game time.
As for Donnal and his ability to play the 4 it will all depend on his ability to hit the open jumper no matter if it comes from the corner on the high pick and pop. On defense he simply can not cover a 4 unless they play a zone which very well could happen. If that is the case he needs to be a better rebounder in his area, meaning get after the ball at its highest point and fight for it.
Chatman on the other hand looks like he could become the odd man out. All the length that has been added means he will have to trend towards the 3 or even 2 spot, both of which mean he will need to handle the ball with confidence and hit the open jumper.
Either way both players will now be in a dog fight for minutes which I like; the more competitive the practices are the better the team will be in the end.
