Late last night, Adam Jahns, a good follow, wrote how Shea McClellin is the new "quarterback of the defense", which is a turn of phrase I don't care for while simultaneously acknowledging that it perfectly describes what you're trying to say.
Anyways, those of you who remember Shea McClellin from such plays as "being nowhere near the ball" and "getting stood up by inferior offensive tackles" are probably using this as a cause for concern, which I won't say is unwarranted. I am willing to say, however, that given Fangio's track record with defense I'm willing to at least give them a preseason game.
