A few other facts about the opposition i have uncovered;

Iowa will have to replace a 1st team AFCA All American Linebacker in Josey Jewell and they also have a 1st team AFCA All American Defensive Back in Josh Jackson who is a Junior who may come out early. If your selected 1st team AA why would you come back for a senior season when you will obviously be drafted if you declared. Those are huge holes for Iowa to fill on D, not that their replacements can't be just as good but that would be asking alot.

FSU also has a 2nd team AA Dback in Derwin James who is a Junior, he may come out early.

Utah has a 2nd team AA PlaceKicker in Matt Day also a Junior, not likely to leave early. He could put on a show in DeKalb. They also have 1st team Pac 12 Punter in Mitch Wishnowsky(JR) so their Kicking game is one of the best in the country and
Both are likely to return
Utah has 2 2nd team Pac 12 Offensive players in WR Darren Carrington II and OL Salesi Uhatafe, both Seniors could be graduating. Only 1 2nd Team Pac 12 D player in DB Julian Blackmon SO, have a 2nd Team Pac 12 Return SPecialist in Boobie Hobbs, Sr. May be Graduating. So they have holes to fill on offense.

James was FSU's only 1st team all ACC player this season, Seminoles have 1 2nd Team Center and a 2nd team DB Tavarus McFadden both Juniors. They do have a 3rd team DT Derrick Nnadi who is a Senior, may be graduating.

2 of the 4 teams are bowling eventhough FSU should not be because one of thier 6 wins wsas over Delaware St. NIU is not playing Alabama, Clemson Oklahoma and Ohio State, these teams are beatable.
