Ohio State really has it hard next season , and vegas odds have them repeating once again , http://www.fbschedules.com/ncaa-16/2016-ohio-state-buckeyes-football-schedule.php
Michigan will be difficult to beat in 2016 with Harbaugh in his 2nd season there. He will right the ship that quickly.
And Penn State has now had two good recruiting classes....24th last year and 11th this year (rivals)..... @ Oklahoma, @ PSU, @ Wisconsin and @ Michigan State would challenge a whole lot of teams, methinks......
That's really NOT a bad schedule, at all. No directional state's on there. And as @Hawker45 mentioned, there are several solid opponents.
I HAVE THEM ON PENNY BETS TO LOSE TWO GAMES , Wisconsin and Michigan to the odds that they will not be in the big game in 2016 Meyer will be back to normal,
tOSU's 2016 schedule (the one you posted) is definitely more difficult than their schedule this coming season (2015)....that's for sure. Harbaugh will be in his second season at Blue and PSU will have regrouped by then, also. tOSU could easily run the table in 2015.....
