Remember how good of a OC Eric Beienemy allegedly was for haivng Patrick Mahommes? He didn't even run the KC passing game and fans thought he was HC material. The QB is the key. You don't need a superstar, but having someone at least better than average is likely crucial. Then, after you have a QB, he'd better have weapons, a running game to take the pressure off and an offensive line. The Saints need help in all of those areas as well.
