Because he has already shown an ability to do it. You talk like the guy runs in molasses or drags his leg from a war wound. He isn't athletic or quick enough to cover most TEs and WRs, or spy and contain athletic QBs. But he is pretty good at getting after the passer. You're tossing the word "elite" around and no one is asking him to be an elite edge rusher. Just go be effective. By all accounts, Telander is a good teammate and his leadership is an asset. He just needs to be put in position to be effective. If he insists on playing LB, then I'd imagine he's already been recruited over, or he can go try his hand at LB in the ACC or CUSA.
