I'll go again - except for Baylor and ND with their Uconn game, none of these teams in the discussion should have been really tested by any of their opponents.
ND was tested by GB. The #2 team shouldn't have that on their resume. They have a win over Washington at home and Washington may be a decent team, but ... 11 point win is OK. Otherwise they have played nobody. I don't see that except losing at home to Uconn as anything better than MD to be honest - Louisville/Washington, ASU/GB and a bunch of mid-majors who any of these teams should blow away.
Baylor - UCLA by 14 at home, Ohio State at home by 17, DePaul at home by 32 - the first two are what they should do the third is maybe a bit better than 'expected'. Other than that, they have played the usual dregs plus TN as their signature road win.
SC - losing to Duke is a non-starter - a Duke team that is now struggling to stay ahead of Elon tonight at home in the third Q. that loss moves them to the back of the chain.
MD - a load of crap with the single best win of this group - on the road at Louisville. Not impressive but in a pretty close comparison to the ND Green Bay game they played a decent ASU at home and won by 41 points, 10X the margin of victory ND had over GB at home.
Baylor and SC have played the most challenging schedules of this group but again for teams in a discussion for a #2 ranking, none of these games should have been hard and they weren't. All of these teams have scheduled Uconn which is great, but none of them have scheduled any one of the others and they all should have. None of them should be particularly challenged in conference, so they should step up and start scheduling not 1 but 2 or three of the top five teams. I am disgusted, they all use that P5 conference schedule is so HARD that they have to play cupcake city in their OOC. I call BS. Baylor has like one loss in Big 12 in the last three years and they haven't really been challenged. ND - they sometimes throw in a conference loss to add a little color, but really? SC - easy street in the SEC even if they can't beat Duke. MD in the BIG Meh? Don't think so.
To me the question between less than great resumes comes down to Baylor or MD, and I come down barely on the side of the undefeated team with the best road win. Give ND 4th and SC fifth (to teach them not to lose to Duke ever again!

)
I like FSU but they just haven't played anyone besides us (best win so far tonight against FL), and neither has Miss State (Texas at home while needing OT to beat Iowa State )
