It's definitely a DE that can bother the QB. Our window is open right now, Beane has to figure this out.
I agree that Beane needs to do whatever he can to find a DE to make QBs uncomfortable. I'd be fine with giving up next year's #1 pick and a 3rd to move from 30 to 10 or so. Or trading a first round pick for a proven DE. Needs to happen.
