At this link is a video with discussion by Mel Kiper about hand size and Kenny Pickett. In it he discusses arm length and I know last year at this time there was a lot of questions about why some guys arm lengths are scrutinized so much.

Kiper goes on to say that "every position but QB and RB, arm length is vital." "whether its tackling, catching footballs, breaking up passes, keeping DE's away from your body, keeping Offensive Linemen away...the bottom line is that arm length is critical."
