Correct, this is what I keep saying. The trend now is to simplify because you can't practice enough and rosters change so much from year to year (and week to week). The Patriots run a very simple system on D, as does Seattle. On the offensive side of the ball, if you don't have a "coach on the field" type like Brady, Brees, Rodgers or Manning, you also need to simplify. Carolina runs a simple offense.
