Carson has been a revelation in Seattle, going from an afterthought to a true bellcow running back during his four years in the Emerald City. The challenge with Carson is durability as he's only appeared in 45 of a possible 64 games in his career. When healthy, Carson is a skilled and tough running back capable of putting up RB1 numbers. His free agency will be one to watch. Do the Seahawks dare let their best runner leave now that they've re-committed to running the ball more? Are they going to be outbid by a team like Buffalo or the Jets who could target Carson to be their new RB1? It's going to be a wild ride for our RB22. Buckle up.
