You are (or should be) playing for the team as well. Your football family. The guys who have sacrificed for you as well.
I don't like kids getting hurt and there have been a few cases of guys with career ending injuries in bowl games, but it's very rare. Even this ankle injury here isn't likely a career ending thing.
Want to skip out on some crap tier nothing bowl? I don't like it, but I can understand it (still don't respect it), but major top bowls? Go get glory to end your college career and do it for you, your school, and your teammates. The ones also leaving and the ones staying that helped you get to your draft slot to begin with.
