I'd just like to add in my two cents here.
First of all, everyone always compares great teams with the Colts, and with good reason. But where has the Colts' offensive capabilities gotten them? They've never gone to a Super Bowl despite having one of the best offenses of all time. The fact of the matter has been that when they get deep into the playoffs, eventually one of the other teams successfully utilizes the "Peyton Formula" that Belichick uses year in and year out in the playoffs to factor him out of the game.
An interesting fact I found was that we actually increased out sack total by 13 sacks last year from 24 to 37. But what appeared to me to be a glaring problem was that our opponents' offenses would be out on the field for long chunks of time just whittling our defense down. Plain and simply put ladies and gentlemen, that's not a defensive problem. That is a problem with the offense not taking it's time on the field and giving the defense time to rest. You can have all the impact players you could ever want, but if they're playing for 40 minutes a game, they'll give up big plays.
Now, the old addage that "defense wins championships" definitely has merit. Just look back to the Bucs and Ravens Super Bowls and you'll see what I mean. But the thing to understand is that it's not the ONLY way to win a championship (the Rams, for example). But you have to understand that every offense that is incredible and wins a title will always have an above average defense that doesn't get any coverage.
So what's my stance, you ask? Well, I was pro-Bush, I thought he could come in and change our offense for the better. But here's the reason why I think they didn't opt for him: We have so much money tied into Domanick Davis right now that getting another premier running back would lead us in a few year into the salary cap hell the Titans are still pulling themselves out of. And frankly, I'd rather see us get progressively better and have many shots at the title in a given period, rather that that one chance the Titans got. But I'll say this to those fans that are extremely disheartened...We gave both players a very in-depth look and decided that Reggie wasn't our guy. These guys are paid a hefty sum to get this right, and the people complaining on this board and around the league have likely never seen Mario or Reggie in person.
