Rak may be more out of position because he's being played out of position. Like Rick Jackson in year's past, he is far too slow to play the wing, and hasn't had enough time in the middle of the zone to really judge whether or not he has enough knowledge to play there. Like someone else mentioned, Baye goes for every head fake there is. Even if he affects the shooter in the middle of the lane, too often that means an offensive player behind him scoops up an offensive board and a put back. (To be fair - Fab is guilty of this as well.)
The one thing that really perturbs me about Baye is the fact that Fab was able to learn how to hold his position and get an offensive foul, yet Baye still trys to jump and get the block against offensive guys who are out of control. I have only seen him try to get one offensive this year.
