I agree, and this roster should be able to take us to the Super Bowl if Garrett does his job.
I'm always cautious with expectations, keeping in mind worst-case scenarios.
With S George Iloka, it would be that he improves our run defense but hurts our pass defense.
With DE Robert Quinn, it would be that he's not an improvement over what we got from Gregory last year. (Maintaining the status quo isn't good enough.)
With DT Christian Covington, it's that he's a role player at best, only giving us what we got from players like Caraun Reid and Daniel Ross.
With DT/DE Kerry Hyder, it's that he's not able to get back to form after the major injury he had following his one great season.
With WR Randall Cobb, the same thing ... that his injury issues have made him much less of a player than he was.
With TE Jason Witten, it's that his decline is accelerated by his year off.
Now, I expect us to hedge our bets some in the draft at safety, DT and possibly tight end, but we're not drafting until 58, so there's less of a chance that we're going to hit on a big-time player with those picks. (And other teams that were already better than us have first-round picks to try to improve their teams even more.)
Again, though, this is the possible downside with these players. The reward if they all return to their best form, or even near it, is what the team is betting on, and I hope it's what we get.
