Not sure why you would use a receiver, there's are better comps, there are plenty of others but that's better than being Mingo 2,
Tolbert has made some big plays, and he had really good one year when they actually made him more involved, not that bad player. imho Jag, yes, BUST, NO.
Stop the negativity,
here's some positive comps,
it took Rico and now Davis, both RBs for the DC More than develop and then come productive I think Davis is right there on the bubble to do the same thing that Rico's now doing,
That is a very good comp, because it took up a while to have the game feel more natural and slowing down to where now they can actually just go play.
