Age and football
This movie has discarded the entire comedic premise of an adult pretending to be a child, along with all the possibilities involved. It has even discarded the entire need to lie about age. And yet Jonah's character lies anyway and says 19.
When I was at college my most respected peers were all about 27. No comedy in the fact really.
ALSO, here's a thought : They didn't even make use of the fact that Tatum's character might struggle at football when going up against the younger players.
Sport: The one area where age could have mattered in this movie and they didn't even capitalise on that?
Come to think of it, the heavy drinking could also have been an area where age makes itself felt, and they didn't even capitalise on that (on balance they did a respectable job of taking what was thtrown at them).
