I live in the Sarasota/bradenton area. I have been to a few IMG football games. I don't think their model works for a sport like football. The main issue is: they cannot find a representative schedule. The local schools that have talented enough players to move on to play in college do not play IMG. This is due to some poaching. They do play a couple of prep schools but the majority of their games are played against inferior talent teams.
Much different than say, Prep school basketball. I question how a kid is going to get better playing against significantly inferior players. One game last year, IMG lined up 5 kids across the line on offense avg. 6'2" 280 or better. Biggest kid lining up against him was 5'11" 250lbs. So your ability to develop as a player is limited to practicing against your own team. At $54K a year in tuition it seems odd to pay this amount with a college scholarship being the goal.
The atmosphere is terrible as the kids are there for individual goals on the field and in the stands. It's a bastion of "entitlement" for 15-18 year olds yet to do anything.
I will say with a diamond vision scoreboard, SmoothieKing and SubWay counters, college level locker rooms, top tier field turf...the most incredible facilities you can find anywhere.
