Milo Eifler is track level fast. If he plays the MLB position (and plays it well), I can see considerable growth, considering how much pressure a true tampa 2 D puts on the MLB to read and react.The question I have is, how much will he gain next year in these two aspects.
Of course, Beason is similarly speedy, and I think Hobbs and Adams are good players already, I dont think finding a 4th and 5th DB should be overly difficult, a few players showed flashes this past year.
Getting Cooper/Mathis would both be huge. I think if our interior linemen can get healthy, and Roundtree and Gay improve, the defense should be much improved. Individually, the players seem at least decent on paper. Depth might still be a question, and a lot still has to line up for this thing to work, but I believe we are in a good spot to improve dramatically, that also hinges on Lovie helping big time.
