Parity is the key and the NFL has done quite a bit over the years to allow each team to have a shot each season. I think they've done a pretty good job at that until it appeared they started involving the refs to "assure" parity, if things aren't going their way.
IDK, I guess we have to come up with another formula when it comes to scheme, coaching and players. In order to have a dominant defense, we'd have to take a hit on offense and visa versa. Not enough picks and money to go around. If you try to do both, you end up with neither side of the ball being that good. We have to find those guys (Like we have in the past) that are diamonds in the rough and that calls for our scouts, trainers and coaches. Seems as soon as we get some great coaches in here, someone steals them and they take a few of our good players with them. THAT's what I think has held us back the past couple years, more than busts on draft picks. We have to find a way to keep our good coaches here. JMO
