Hes an excellent talent on the field and off the field. To have that from those that were staying and with the new GM (Michael Lombardi), Coach Belichick coming in theyre saying the same things. Theyre like, We know that he can make plays. This is the kind of kid that we want to have here. So just going through that just being reassured of that made it known that thats where we want to be.Austin Alexander and his family spoke with Belichick by phone for nearly 30 minutes Sunday afternoon. The longtime former NFL coach explained how he likes Alexanders versatility.When youve got a great man like Coach Belichick and hes referring to Austin even some of the past (New England) Patriots that hes had hes like, Man, I really think that he could do this or do that, Durran Alexander said. So it was cool to know that he did his homework and knew that Austin was a defensive guy, he was an offensive guy he could be inside, outside. He spoke to all those things.Austin Alexander completes his high school career Friday and plans to meet with the UNC team Sunday in Chapel Hill.Alexander plans to practice with the Tar Heels as they prepare to play the University of Connecticut in the Wasabi Fenway Bowl on Dec. 28.
