UNDATED (AP) – Big Ten football teams are getting two Saturdays off for the first time this year.   Iowa coach Kirk Ferentz says there are a lot of unprecedented things happening these days in college football because of conference expansion.   The byes give players a chance to rest and relax during two weeks when the regular season starts in late August and ends after Thanksgiving. Coaches, meanwhile, evaluate their programs, players and plays before hitting the road for recruiting.  Teams – such as Indiana against Penn State – have taken advantage of having two weeks to prepare for a game they ultimately won.  The Nittany Lions, coming off a bye, hope the extra time they had last week helps them upset No. 4 Ohio State on Saturday night.  The Badgers have a bye weekend.
