The best "D", no. Carolina, San Fran, Seattle... they're loaded with talent that Buffalo can't match yet. Especially in run defense. If Barr slipped to us, I'd take him in a heartbeat. So much pass rushing skill, he'd be a double digit sack guy immediately. I don't think Mack is a good fit here in Pettine's defense, but I know that connection won't go away.
