How about wtaching 5A ball, playing 5A ball, & college ball. Does that count? Well, you hit on it. The athletes are bigger, stronger, faster, and SMARTER. This changes what works and what doesn't. Don't discount how much these changes effect the game of football and gameplans on both sides of the ball. It makes all the difference in the world. Offenses & defenses are so much more sophisticated at this level. To help you understand, it's why the countertrap is a bread-n-butter play for many High Schools but a rarely run play in college. It's why the option works in college but not the NFL. It's the reason we see lots of zone blitzes in college and the NFL and not in high school. In high school 1 player can dominate a game and teams can gameplan an entire offense/defense around them. This does not happen at the next level. It's not so much as SMU & FAU have surprised our coaches with freakishly new things, football is still football, but I do believe that the cliche "putting your players in positions to succeed" is the gospel at this level. It all boils down to understanding the physical abilities of your entire team, your opponent, and adjusting to that when need be.
