It was something that gus mahlzan wrote in his book while he was still coaching in high school.. some of the benefit of what they were doin is because it was something most defenses never saw or how much time do u devote to one team running a "gimmick" offense that some coaches with hubris didn't respect even.I do wonder if this will happen.
Offenses because faster and more spread out to take advantage of slower, bigger defenses
Defenses became faster, and smaller, to keep up with faster offenses.
At some point the pendulum is likely to shift and offenses will become bigger to take advantage of smaller defensive players. And in turn, defenses will be some bigger and likely slower.
Some offensive coach will figure this out and the pendulum will start to shift back. Such are the adjustments in sports.
Nothing is forever.
When half your conference is running it then u can devote more time, coaches devise better schemes, u can recruit to defend and players see it more week to week so get more of a feel for it.. Since the spread revolution in mid 00s has dominated from high school, to college to NFL.. even though best QB in leage is a air raid product in an offense that fits him we still have post on CIS dreaming of I formation. We are last team to join the revolution 20 years later and defenses are better to defend, lol.. of course!
Saw this video couple weeks back, I doubt pendulum swings all the way back but watching dolphins and obviously the concepts come from 9ers, u see how they use the position. Also talks about positionless football and how rams use a big wr to play position and gain advantage on nickel defense.. makes u wonder as Mario has had both rams and dolphins coach at his camps and that undersized te we recruited from Vegas and what his role could be in future..
