Looking further down, maybe USC is just snakebit?
They are done with B1G play at 4-5. The only home loss was to Penn State and that was in OT. The other home games were a blowout of Rutgers, a three-score win over Wisconsin, and a solid win over Nebraska. All five losses were one-score games. They are literally five plays from 9-0.
Seven of USC's nine games have been decided by one score. Wisconsin is their opposite. Their three point home loss to Oregon is their ONLY one score game. They have big losses to PSU, IA, USC, and UNL. They have big wins over RU, NU, and PU.
You might say "well everybody beats RU, NU, and PU big" and to an extent you have a point but Wisconsin's 46 point win over Purdue was the second biggest MOV in the whole conference this year (behind IU's 49 over UNL and ahead of tOSU's 45 over PU and M's 44 of NU). Wisconsin's 35 point win in Piscataway was Rutgers' worst loss this season. The Badgers' 20 point road win over Northwestern was comparable to tOSU's 24 point road win over the Wildcats and if you adjust for HFA it was equivalent to Iowa's 26 point win over NU. My point is that Wisconsin is hard to figure out because their wins have been REALLY good, best-in-the-conference good but their losses have been REALLY bad.
Rutgers is another team that has kept their fans entertained. They are 2-3 in their five one-score games.
With Nebraska I think you have to just treat the tOSU and IU games as offsetting weird results. Given the rest of their results there is no way they should have been that close to tOSU nor that far from IU but they were.
I frankly think that MSU is better than most people are giving them credit for. They had to play five of the top-6 teams in the league and they went 1-4 in those games.
UCLA might be the most unpredictable team in the league. They have respectable road wins over RU and UNL but a team good enough to win those shouldn't have lost at home to MN and USC.
Northwestern is just plain bad. Their two wins are over the worst two teams.
Maryland, notwithstanding the USC win, is worse. The Terps may actually be worse than . . .
Purdue is winless but they do have two OT losses and an additional one-score loss.
