Your numbers are WAY off, playing ball and going to school does not add up to 80 hours a week. When school is in session you are limited to 20 hours a week of practice including the games. Now sure there are some bending of the rules on what exactly is reported, but as a whole they are followed pretty closely. Allow for a 10-20% cheating on those hours and you are at 22-24 hours a week, not 40.
Those 20 hours do not include film study which I think most starters would want to put in an additional 5-10 hours a week. Some 2nd string guys will match that and in my experience only a handful of 3rd string or lower will bother with extra film time. So add 10 hours of film study for say the starting QB and you are looking at 30+ hours a week of football related activities.
I am sure you think I am proving your point, but you are wrong and here is why...
Regarding school, almost no one takes a full load of hard classes during their season. I went to a school that was on the quarter system and I was required to take 12 credits to be considered a full time student and be eligible. I also, like many others red shirted my first year basically giving me 5 years to graduate. My first Quarter at school I took 15 credits because I knew I was red-shirting I believe the classes I took where very general and fairly easy, classes like Geology 101, Psych 101 and World History 101. I remember my counselor told me and many of my classmates to ease in to college life because that 1st quarter would be culture shock. He said the Winter and Spring Quarters were for your degree the Fall Quarter was for electives and maybe one class in your major. I think I had 10 hours mandatory study hall that 1st Quarter which put me at 25 hours of school, more than enough to pull good grades. So in total I was between 40-50 hours a week school and ball, very manageable. I also took at least one class every Summer Quarter to because that way I still got a Scholarship Check. By my 5th year I was done with my degree and took one 2 credit pass/fail class during Football Season. I was volunteering at an Elementary School few days a week that had kids with horrible home/living situations and I had to write a paper about my time there.
As far as your claims about recruiting I would tell you that you watch too many bad movies because that is not the norm. I hosted many recruits in my time and the coaches gave me the allowed $20 to take them out after dinner. Yes, I bought alcohol shit like Keystone Ice or Pabst Blue Ribbon which left us perhaps $10 to grab burger a 2am. At no time did I or anyone I hosted with arrange for a recruit to get laid. If a recruit got laid on a trip it was purely on him and his game, looks etc. I am not naive enough to say that never happened at any school ever, but it is NOT the norm.
I almost feel stupid for arguing with you because it is obvious you are just ignorant on this subject. Yes, the shit you claim can and probably has happened but it is the exception and not the rule.
