ESPN: Best backs in the league

[MTK]

9. Clinton Portis, Washington Redskins
Watch: Portis highlights
Superpower -- Portis is simply impressive in terms of production. He is near the top of the league every year and is a tough player who will fight through bumps and bruises. He attacks the line of scrimmage and can make the first defender miss in the hole. He does not have elite size but knows how to finish his runs.
Kryptonite -- He puts the ball on the ground too often and at times does so in critical situations. He can be aloof when he needs to take care of the ball, dropping easy passes to kill drives and missing blocks in pass protection. He has great physical tools but at times seems to check out mentally.
