Looks to me that this off season would be a good time to go after veteran WR's who still want to play to go with Austin-Marquez & Britt.
They need to make a serious effort to get GRob to complete the conversion to Gregzilla. Of course, Greg needs to buy all in on this.
The rest of the young 'uns on the OL need some serious upgrading to become a solid NFL OL. I don't know if we could use another veteran blocker or two, but we seriously need some consistency for TGII/Tavon to dominate and for our mystery QB to present a serious defense stretching threat.
I really like Case' savvyness and mobility, but I prefer a QB with a stronger arm, good-great field vision, an good-great accuracy to lead this team---if not right away in 2016 then at least while being seriously groomed. And I prefer a veteran too since it would be a shame to waste all this defensive talent waiting for a rookie QB to get up to championship level.
