1) Part of it is scheme. Even if Superman was at DE, he'd have trouble getting sacks when the defense is laying off the receivers and giving them 10 yard cushions -- maybe it should be called king sized feather beds instead of cushions?
2) I don't get it. Almost any coach with a few firing neurons can coach a great team loaded with talent. That's hardly an endorsement of any sort. It doesn't make a great coach. A great coach is a coach that can take a very average group of players and transform them into a crisply executing machine. For example, Jeff Fisher's team ripped off 10 straight wins and most of that with a backup has-been QB. Bill Belichick has the Patriots right back in the hunt for the AFC East with a backup QB that hadn't played a game since high school and many other injuries. On the other hand, you have Norv Turner, with one of the deepest rosters going and he's firing coaches off his staff, having Rivers throw bombs constantly, etc., etc., and losing a lot of close games. "Jauron is an excellent coach that just needs better talent to win," simply rings hollow.
