Monty would rather them play rather then let Davis develop just to get a win(which I don't believe he would do)
Monty certainly makes player development a priority. That's why Austin Rivers has been getting the minutes that he has.
I don't know why Davis hasn't been playing that much. Its probably a combination of everything in this thread and the other ones. That is the one position we have good depth at so he has to split more minutes, the ankle may be an issue, they might be worried about him getting beat up too much, etc.
