We are limited at QB. We are limited at WR. We are limited at O Line. We are limited at RB. TE is at least average, maybe. Fidone is a big target and has shown he can go up and catch balls no one else can get to. I don't see the elite athleticism in Fidone I hoped he had, but he may have lost a step or so with his injuries. I still give the TE position an avg rating. The rest of the offense... below avg.
So QB is not our only issue. A big issue, for sure, but not the only one. We sorely need a difference maker at QB. And RB. And couple of WR's. And offensive Tackles.
But a difference maker at QB would be the biggest boon that a single player could bring. QB is that important to an offense.
