I see Clemson (18, 19) and ND (24, 25), any others that you know about.
Texas plays at USC, v Maryland and v UCF next year. At Maryland and v USC (18), LSU (19), at LSU and v USF (20), at Arky (21), at USF and v tOSU (22), at tOSHU (23), Michigan (24 & 27). Basically, Texas has created a system of playing a blue blood opponent and an additional Power 5 team in home and homes. With our third game being against a non-cupcake non-power 5 team (No FCS).
Texas of course plays in an easier conference but will still be playing against 3 or 4 top 25 teams during conference play. I don't blame TAMU for scheduling a lighter OOC schedule
but I think overall the two differing approaches balance out SOS. Both teams have had respectable SOS recently (2015 7 vs 25, 2014 14 v 6, 2013 11 v 26, 2012 12 v 6).
