In reference to dcm's point (only because I mentioned the same thing) Mornhinweg made an interesting comment this afternoon as well. He basically said he's still convinced Geno can be a great one some day. Maybe he's committed to Smith as his future starter here.
Honestly, if Marty truly believes that he can mold Smith into a star, I would sit through another year of him. Draft the pieces around him that are needed, like a receiver in round 1, and see if next year there is true progress.
Then, if it doesn't work out, we go all out to get the future franchise in the 2015 draft.
It certainly requires more patience, but that is the price of this not having been a true rebuilding year.
