I am not sure how much Mich St and Penn St still care about bowl elligibility, but both teams need to win their last 3 games to be bowl elligible.
This might still be realistic for Penn St. Their last 3 games are @MSU, Neb, and @Rutgers. All are winnable games. The other question is, if they make it, will they accept the bowl bid? They are probably overdue for a Pinstripe bowl invite
For MSU, its not impossible but not likely they can win out. The play PSU, @Iowa and MD. If they pull it off, their reward might be the Detroit bowl.
