If my answer is a hesitant "yes"? WTF?
Ahoy, Captain Obvious, you are asking if a struggling 3rd year OT, that seems to be slowly improving can immediately compete effectively with the best DE's in the NFL? Is that supposed to be some kind of "gothcha"?
Because if so, it's mighty weak.....so, obviously NO, right now he is not at a level necessary to effectively block the best pass rushers in the NFL, but that doesn't mean he won't or can't get there.....How long? No idea, I'm not a soothsayer after all.....
