Jackson is serviceable. Queely is not especially dynamic. Cooper moves the needle a little.
But among Hatcher, Gadsden and Alford someone has got to emerge. The new coaches (OC, QB + WR) will see to that. I mean if any kind of talent is there the new coaches will manifest it, or at least scheme it to put them in a realistic position to be successful.
There's also a guy who lines up on the O-line that I think they can pass to. Maybe they discover him. The TEs in the NFL are all over the field and not just used for blocking.
