"There was a time in rookie camp where they would have us go up and draw defenses on the board. Our base 'D' at Alabama was their complicated 'D'. It got to a point where everything out of my mouth was going to shock those guys. I would go up to the board and draw things and the coaches would be copying it down."
-Javier Arenas talking about reporting to camp as a rookie with the Chiefs.
I have to believe that this is, in part, Javy being Javy's biggest fan. The guy is prone to talk himself up.
With that said Saban runs an NFL style defensive system. Once installed there is going to be better continuity then NFL teams enjoy. Bill Walsh ran the exact same offense at Stanford that he ran at San Francisco, with a few additions. Last year Jimmy Ray ran an offense that is less complicated than most college offenses. It's not uncommon for NFL teams to simplify what they do or for some major college teams to run advanced systems.
If what Javy said is true I think it's more of an indictment on what the Chiefs do defensively than anything else. I have a hard time believing that NFL defensive coaching staffs need to learn anything that Saban or any other college coach does. Emmit Thomas and Romeo Crennell are on that staff, they know what they're doing.
NFL offenses are typically much more robust than college offenses and they attack defenses in different ways. NFL defenses therefore focus on taking different things away than college defenses. It's a chicken and egg situation. I have no doubts that Saban's defense at Alabama is essentially the same as his defense at Miami, with a few tweaks. I can even believe that it is more advanced than what the Chiefs run as their base defense - remember the Chiefs are a young team with only a second year head coach and a ton of young starters in their defensive personnel. I also doubt Javy had a head up on Eric Berry, another rookie.
Had Javy walked into a Patriots, Jets, Steelers, Chargers, Eagles, 49ers, Saints, Ravens, Raiders, Giants, Bears, or Packers training camp his head would have most likely been spinning.
