The screen is not a run, it's a pass... That's why the dolphins blitzed in that situation, expecting a pass there. And there is a reason why CJ is the leading receiver on their team.. he has more receptions than anyone else on their roster.
Nah no question the screen is a pass . . . but it usually a great screen pass play requires alot of YAC, I just don't want people to forget about that play and think Chris Johnson didn't have more than a 12 yard gain.
