God forbid that Bush gets hurt, Thomas will be asked to carry the full time load and either LJ or Hilliard will be the guy softening the workload. Rookie running backs taken much later in the drafts have been able to be a fulltime workhorse. Is it ideal? No, but even if Thomas is coming along slower than they hoped, I am sure they still have enough confidence to allow him to be a #1.i just hope these guys have a backup plan...if when reggie bush gets injured cause odds are damn good he will at some point and d thomas is gonna take an awful lot of hits the way he runs...and i hope that backup plan isn't lj and hilliard...cause we're gonna be in a world of hurt if it shakes out like that
Now, this is all assuming that something bad is going to happen to Bush and he will miss time. The main plan is NOT for that to happen. If it does happen they have their #2 draft pick to step in and have a veteran in Hilliard or LJ to share some of the burden. You can't have three Pro Bowl running backs just because you are scared that one of them might get hurt. In a perfect world, Bush and Thomas share the load and a guy like Hilliard or LJ get a couple of carries here in there. In a non-perfect world(Bush gets hurt) you go with the rookie and a veteran backup. Or maybe Thomas goes down and they need a power back to team with Bush and in comes LJ or Hilliard again.
Also, if any of the top two get hurt, it doesn't necessarily mean they have to go with LJ and Hilliard in the rotation, they can always sign another free agent off the street. Heck, maybe our 3rd string running back isn't even on the roster at the moment. The LJ signing to me is more of a kick the tires kind of signing. In just under two weeks he could easily be sent packing and the Dolphins could claim another back off waivers.
