I wish Deon the best, and I can get over the small size or lack of physical play, but my big issue with him has always been his body-catching style. If he were a strong 'snatch the ball out the air' player like Rice - Deon is probably an NFL player. But, a small body frame and body catching means that he's a non-factor in traffic.
Remembering rookies will play like rookies, since 2012.
