I wasn't impressed with Miller until the 4th quarter...they he took over and i enjoyed watching that. The refs were questionable throughout the game but you can't expect much from high school refs.
Can someone closer with the Mason program tell me more about Middleton? What year he is? Who's looking at him on the next level? Just stuff like that. He seem like a solid player from what i've read.
Tell the players to get up in someones face and play defense. There is such thing as 5 seconds. Plus, at the high school level tough defense will almost always eventually force a turnover.
