When he came out of college everyone (draft analyst and yours truly) said he was the most complete back since Emmitt Smith as a runner, receiver, and blocker. He is not elusive as Smith, not as fast as Eric the Great, not as sweet as Sweetness, not as dominate as Jim but has that contact surge forward that Smith, Brown, Payton, and Dickerson had on the football field. In the second half that contact surge leads to +20 yard runs.
You have to want to block. Smith and Payton had the want to and the skills to block. Jim Brown did not want to block. Elliott has the want to and the how to as a runner, receiver, and blocker. It is very hard to get rid of an all around RB (see Frank Gore and Adrian Peterson). You can always use that type of RB in an offense.
I hope he is getting those massages after games that Emmitt did to prolong his career (he rushed for +900 yds, 9 TDs his last season). He will need it after the Seahawks game which I predict he is going to rush for way over 100 yards (if the Big M&M and Boy Genius give him the ball).
