There's no logic or science behind what he or you are attempting to convey. Where a player goes to college has no bearing on how tough a player is, or how they behave in the NFL. It's just some weird SEC infatuation, fella.
Yep. I mean certainly environment has some effect on who a person is, but it's impossible to predict how each individual will react to that environment. Drug dealers and doctors can come from the same place. It's all how each individual reacts.
And, in the case of college football programs, it's not like OSU is vastly different culture wise from Alabama, LSU, Georgia, Florida, Texas, Oklahoma, USC, etc. These are all high profile programs that have "attitude". I mean who has more attitude than Alabama and LSU players? I mean Joe Burrow is all about swag. And the dude grew up in Ohio and played for both LSU and tOSU.
The truth is that all people are a result of their genetics and environment but you never know how a specific individual will turn out based on those factors. Moreover, it's impossible to know what each person's specific environmental influences were, much less all of their genetics. Psychology itself isn't a hard science and trying to categorize people based on their environment is pseudoscience do your own research at best.
