Has he improved? Yessir. That's all we're looking for from him. Can't expect him to go from where he was last year to a good qb in one year. He's taken steps, that's all I've said.
When your GM is likely out the door with the coaching staff being also possible, the likelyhood of a new QB is there though.
I know for a fact though that i've never listed Gabbert as a "good nfl quarterback". Have I said he's had good games, or looks like he could be a good QB at times? Yes. But no, i've never said he was good.
