Terry P,
Just looking at the Safety position, there has not been a guy that has really stepped up at Johnson's old position. Not olny do you have to be smart, but ability to cover the angles with speed and timing, and good coverage skills. Dre has the size, and ability to play a corner, even at his larger size. Now if he can hit, like I've read in a few other places, that is good for run support. I could see him getting the feel at nickle and then becoming a starter by season end. Corners usually run about 6 foot or less, safetys are around the 6-2. If he is smart like a safety and can cover the field, and cover like a corner, run him to safety. Put some muscle on hima nd you have a George Teague.
It wouldn't hurt, only help. We can continue this dicussion in about 4 months....?
