Note that their games at South Carolina and at West Virginia are also part of the Cancun Challenge. Playing in a four-game MTE allows them to have 13 OOC games.
With the exception of those two P6 conference teams plus Northeastern and Vermont, that is a weak schedule. They should run up a good record heading into PL play. They will likely be favorites in nine of the 13 games. I wouldn't want to see Bucknell playing that weak a schedule, but I wouldn't mind seeing a few very beatable teams among the 13 Bison games.
