Jrry old buddy. Hope you are doing well. You might like this. Are you describing a ballerina (smoothness, nimble, graceful) or a football player?

I do agree with the line of thinking somewhat. He's not overly quick-twitched, he seems to mirror/diagnose, adjusts and gears accordingly. Kind of like scratching gears as he shifts. He's not often giving up any separation whether on an island or in the slot. But in the third, it's hard not to like a slot cover guy with the other items you mentioned.
You know the drill better than me. Now if you agree somewhat with waiting on a corner and the Rams very well could wait if they pick Clowney or OL at 2, you might be able to take guys like Evans or Donald at 13. That wouldn't break your heart, would it?
You may be right about the Tampa 2 scheme as a best fit because Gaines is not a grabber in his press and his chuck/redirect is not real strong or important to his coverage game. He seems to turn himself into the nickel festering in your pocket. Drives guys crazy and off their game. I've been on both sides of that fence.
