I believe he skipped classes and didn't do much if any school work. I assume the players have to lift or do some kind of conditioning every morning . I also assume their are practices every day. Plus some kind of film work. I assume Harrison and the other guys attendance was near 100 percent . On game day the players stay at a hotel and are together for much of the time before the game, walk throughs . It is obvious he missed certain team events . But I don't believe he was missing as much as some are saying. No way the other players would stand for that.
