Vinny tips his hand on the final 53

Only late in the preseason can there be a 40 post debate about our 3rd and 4th string RB, lol.

Here's my take, unless Aldridge really struggles, fumbles or gets injured tonight he's on the team. He becomes a Leon Washington type player, not a true backup in the true sense of the word to replace Betts, not a 3rd on the depth chart guy lock Rock. He's a change of pace player, getting 5-8 snaps a game with the hopes that he make a big play. By Vinny saying 5 backs (including Sellers) are likely means that it will be Rock plus either Mason, Dorsey or Aldridge.

If it were purely about the 3rd RB position, then Mason would probably beat out Rock because he's a better RB than Rock is, but Rock is that guy who does a little bit of everything on ST well and you can't replace him with a guy who doesn't play ST.
