I just watched the first film of Shallman as a RB running over people and am not sure what this kid will grow into since I have not seen him in person. I would be interested in projections based on what others have seen as to how much bigger he could get.
I pulled sizes from Gerhart (I thought he was bigger) since he just ran over people last year, Jacobs since Borges made that comparison and Okoye since he was just a big dude. I was surprised to see that Shallman is likely be bigger than all of those guys. I used Scout profiles for the H.S. information. Shallman is already listed at 6'3" 248 assuming that is correct.
I guess the key would be to see how much his speed can improve since the guys above are running in the 4.5 range or so we are led to believe. Borges was obviously spot on with Jacobs' size since he has coached him. I wonder how much taller Shallman could get.
