@McBolt the first few seasons (in particular the opening season) are going to produce wild stats (outside of passing) due to a few factors.
1. Wild mismatches - eg a team drafts a stud at DE his opponent doesn't draft OT until round twenty
2. People are still adjusting to life in 4.6 - if you can't block, you can't win
3. Free agency doesn't have any real effect on the quality of a team until season 4 or 5 and beyond. Especially if playing in a full league where owners renew/extend contracts (without using the renegotiation 'wizard'/dunce, which just guarantees cap **** and three seasons playing catch-up)
The top 'sackmaster' in Beast Mode had 26 (five more than next best) that's not beyond the realms of possibility in real life. Those teams getting a QB hospitalised on a weekly basis need to improve their OL's and get protection.
Look around the best half dozen teams in all leagues and they won't be giving up more than 2 or 3 sacks per game , whereas those teams in the bottom half dozen (in all leagues) will be giving up 6+ sacks per game.
