Team B because Team A has that loss against a Top 201-250 RPI team. Also Team B only has two losses and a very similar non-conference SOS despite having a weaker conference SOS. Team A is Kansas, Team B is Gonzaga.
You and BigBake guessed the teams (you guys are fast!)
I can accept your argument for B, although I'd go with A (and it's close).
Maybe I'm crazy. I posted the comparison because I assumed I was missing something. The high-profile Bracket Boys, Lundardi & Palm, still have Gonzaga above KU (and both have GU at a 1-seed -- I won't argue that either way right now) -- Palm has 2 seed lines between the teams. I don't think I could find 4 resumes to drive between those teams, either way.
The obvious black-eye for KU is the TCU loss. That almost guarantees KU won't get a 1-seed. But between these two in the pecking order, check the rest, especially opponents involved in each team's "big wins" (top-25-ish):
KU-GU
It feels like Gonzaga is getting more credit than KU for beating the same Big 12 teams.
I know, all of GU's wins vs. Big 12 were away from home, but KU also beat KSU in a true road game (GU's was neutral) ... and also, KSU & OU are the only top-25 wins for Gonzaga.
And that's it for top-25 wins for GU. Between that and the St. Mary's (Gonzaga's other two top-50 wins) KU has beaten five teams — Ohio State (road), Colorado, St. Louis (neutral), Iowa State and Temple — with higher RPI than St. Mary's. (I'm not even counting Belmont)
