I don't worry that much about the O Line. It's a unit where there are always veterans leaving, but other guys step up. Cave, for instance, was an All-American, but we haven't actually missed him much. And with the last couple of classes, we've got good depth.
Same with WR. TJ Jones has bloomed into a hell of a receiver. But we've got so much quality depth I think someone else will emerge. We lose no TEs. No RBs. If Golson makes it back we should have our best offense in years.
On D, ILB of course is worrisome. We need Grace to come back strong, or else I really do think we've got to move someone over, especially since there aren't enough snaps at OLB. Can Okwara play it?
If the other thread about Tuitt is correct, that takes a lot of load off the D Line. But we must find a nose. Jones? Really bummed we burned Kona's fifth year for nothing.
But our DBs have nowhere to go but up. And our athletes on the edge (Jaylon, Ishaq, Okwara) are fearsome. Our defense will be OK.
