I'm not an expert on the X's and O's of football but it seems to me that Marvin was incorrectly characterized as a defensive genius after his days in Baltimore. Don't get me wrong, I love Marvin and think he saved this franchise but I think people expect him to be a miracle worker for defenses. He had amazing talent to work with in Baltimore with that defense, I think I could have been the DC for the Ravens that year and done alright. He just doesn't have the playmakers to work with like he did in Baltimore.
Remember, folks, it is just the preseason. Last year the Bengals looked absolutely unbeatable in the preseason going 4-0 and look how the season turned out. The Colts had an 0-4 preseason last year and won the Super Bowl. I think it is very evident that the offense has been super vanilla and they just need to tighten some screws a bit before the season and they will be fine. You hope the defense will be average and force a few turnovers. A lot of the points in the preseason seem to have come off blown coverages by some rookies. I'm not concerned yet, if they are playing like this 3 games into the regular season I'll be concerned but not right now...
