If South Carolina only loses to UConn and then to MSU once (either regular season or SEC tourney, but not both), then they will have 7 losses. Is that too many losses for a 2-seed this season? NC State shouldn't have anywhere near that many, but of course we have to consider SOS. Presently Massey projects NC State's SOS as 24th (not good), but that will likely increase with the ACC tourney more than South Carolina's will (with the SEC tourney). SC's predicted SOS is presently 9th, which is a big difference.
I don't know how Nolan predicts his future SOS, but he has NC State as 14th (it's presently 31st). South Carolina is predicted to end the regular season with the 15th ranked SOS (their present SOS is 15 as well).
Here is NC St.'s remaining schedule (with Massey rank):
@Wake Forest (128)
UNC (39)
@FSU (25)
@Cuse (18)
Notre Dame (4)
Wake Forest (128)
@UNC (39)
@Louisville (6)
Miami (19)
How many losses do you see? (Massey predicts 3)
Incidentally, Massey predicts South Carolina will end the regular season with 9 losses, but of course the Gamecocks are trending up.
