How do we know this? How do we know we don't have the players for perimeter defense? Has Moss gotten opportunity to even show it yet? Are you assuming that Jordan has gotten worse over the off season? Is Conner just bad and slow because he's white and playing because he's the coaches kid?
I just don't know how we know all this stuff already? I know that we lost one of our worst perimeter defensive players and gained a 6'5" 4 star player. I'd imagine that Jordan has improved, but I am not willing to bank on it. IMO, he's just too tough of a kid not to keep working on his flaws. Part of Moss's quick hook last season was when he got lost on D, but at times, he showed flashes of being capable. He's definitely quick enough, athletic enough. If Nunge is going to play the 3/4, a 6'11" guy would seem to provide some perimeter defense? But we can't really count on that out of a freshman. Ellingson... is formidable, but you know what you are getting I suppose.
I appreciate every single posters input, and I am not saying you're wrong. I just personally don't know how we all know this stuff already. A lot of people gleaned a lot of data off of 1 exhibition.
