Positives
Marshawn Lynch is a very explosive player that is a threat to take it all the way every time he touches the ball. He's a very shifty runner that has great acceleration and is capable of running people over. Not only is this player a great runner, but he's also exceptional catching out of the back field. He reminds me of a young Edgerine James, except better.
Negatives
Lynch comes from a Cal team that implemented the zone blocking scheme. This may be a problem, do to the fact that not many teams run it. I look for Lynch to go to teams like the Packers, Texans, or Jets because of that fact. Lynch also seems to get nicked up here and there, not to the extent of AD, but he played most of the 2007 season with minor injuries.
