I think at this point, a USC win helps ND more than any other team on their schedule. Their schedule is ranked 21st in the country by Sagarin (pre-USC), so they'll be fine there. I personally think Michigan will pretty well dominate Ohio State. They may not win by 26 because O$U has a good D in their own right, but I think they'll be in control throughout, and the pollsters will see that, with both teams sporting lopsided losses to Michigan, that ND's other 11 games are a total toss up with OSU. ND's most impressive win right now WOULD be at USC, who will either win the Pac-10 (IMO, the Pac-10 is the 3rd-best major conference behind the SEC and Big 10). O$U's best win is a road win over Texas, also a 2-loss team, but in a conference that's probably worst of all the big six conferences. It's likely they too will win the conference, but I'll give a slight edge to ND should they win. ND's 2nd-most impressive win (presuming the USC win) would be at Georgia Tech, who appears to have a good shot at winning the ACC. Ohio State beat Iowa on the road, dominating that game as well 38-17. I'll call it a slight edge to OSU based on the scores of those games. ND's 3rd-most impressive win was the 41-17 beating of Penn State. Ohio State's 3rd-most impressive was a home game against Penn State that was a 1-possession game until Morelli threw two pick-sixes in about a minute's time. Big edge to ND here obviously. 4th-most impressive wins: ND over Purdue 35-21, OSU over MSU (on the road) 38-7 post-ND meltdown. Slight edge to OSU probably. 5th-most impressive wins: ND's is either of the comeback wins. It depends on whether you think MSU or UCLA is better. I'll call it MSU, since it was on the road. This is where OSU starts falling off big. Either IU or Minnesota (both home blowouts) would be their 5th-best win. Since IU crushed MSU, we'll give a big edge to OSU. 6th-most impressive: ND's was UCLA. Ohio State's was IU or Minnesota. Edge to ND. From there on down: 7th-most impressive: Navy or Northwestern (both road, basically). Conveniently, Eastern Michigan played both, hanging with NW and getting creamed by Navy, so I'll give an edge to ND. 8th-most impressive: Air Force or Illinois (both road). Since both teams' best games were close games on the road against good teams (Tenn and Wisco respectively) and both teams' worst games were home losses to bowl-bound lower-tier teams (Navy and Ohio respectively), and ND played better than OSU in the respective game, I'll give a slight edge to ND. 9th-most impressive: Stanford or Cincinnati (both home). Clear edge for OSU here. 10th-most impressive: UNC or Northern Illinois. Edge to OSU again. 11th-most impressive: Army or Bowling Green. They're both awful, so call it a wash. ND edges: 3 big, 2 slight. OSU edges: 3 big, 2 slight. Washes: 1 I mean, if OSU is to be blown out by Michigan, these two teams will almost have identical profiles.
