It's "scary" when some post the list of edge rushers who we have tried to turn into LB's and failed - but Sam Brooks is an elite athlete so I hope that helps the transition.
Agreed. I'm definitely not a fan of trying to convert H.S. DEs into LBs. It rarely works. Doesn't matter how fast or athletic they are. If they can't diagnose the play developing, all the speed in the world doesn't matter.
That said, I thought I'd read here that Brooks has played standing up before, maybe even as a safety? If that's the case, I'm a bit more optimistic about him.
