I believe it was on Pardon The Interruption (PTI) that I saw Steve Young being interviewed, and Michael Wilbon spoke about how felt like the NFL today was a worse on the field product that in years past and asked Steve if that was correct from his point of view.
Steve answered back that due to all the player safety restrictions that players and teams are spending the least amount of time together than in the past. With spending less time together, players and teams aren't developing nearly as well and teams have struggled to run more complex schemes because they're not working together as much and there is less time together.
In a reaction to that, a lots of defenses have gone to a lot more extremely simply schemes... and smart QBs like Brady and Brees are tearing them apart, because they're so simple and that he's jealous as he wish he could play against defenses that where as simply as they are today. (so simply schemes are both good and bad).
But Steve Young point is that due to the restricted time together, the NFL is becoming a lot more like college football in the simply schemes that they're running... and that the restricted time is negatively effecting the football product in many different ways, from players and scheme...
I'm feeling more and more like the CBA (or the time restrictions) is ruining the NFL to a degree... as players (around the whole league, not just the NFL) aren't developing like they used too... and honestly I can't remember a year with such horrible OLs to start a season from across the entire NFL and the OL has to be together to try to act as 1.
