Most college football teams have only two games remaining on the schedule, and with so much at stake—bowl eligibility, BCS bids, etc.—the lines sometimes tend to skew (even further than usual) toward home teams.
Public perception says that crowds can shift the outcome in some of these late-season contests, which isn't entirely untrue. If a fanbase knows its team is playing a must-win game, it is sure to show up in full, unlike earlier in the season against FCS chum.
Because of that, these later weeks present an opportunity to get some juicy road teams at a value. Squads that are vastly superior to their opponent might be giving less than a field goal, and sometimes they're actually underdogs.
That is a consistent theme in the Week 13 version of best bets, though it's obviously not an absolute rule. Happy wagering!
