I haven't heard it put quite this way, so let me unveil my latest theory on why it's important for the Pats not to get a lot of injuries. Often we assume that it's because injuries take better/star players off the field, and replace them with lesser talents. Certainly that's part of the story, but here's another way to look at it: An injury removes from the field a player who has had time/game experience in BB's system, and replaces him with someone who has had less. According to my theory --- and here I'll exaggerate to make the point clearly --- we could fill up the roster with $800,000 salaries, and if they could play a full uninterrupted season in BB's system, we'd win the Super Bowl. Notice how by November/December/January we always have about the best defense in football? Players (especially newer Patriots) have had time to experience the learning curve. Injuries disrupt the learning process, but eventually a Randall Gay ('04) or an Asante Samuel or a Eugene Wilson ('03) or a Russ Hochstein ('03) or even an Ellis Hobbs ('05 I wish) can help you win the Super Bowl. The main problem with a patchwork secondary isn't lack of talent, it's lack of game experience in the BB defense. Consequently, the draft is important for securing young players who won't get injured as often (and here I'm not positive that statistics back up this assumption). That way, we're more likely to have a healthy year which equals a successful year when your coach is better than the rest!
