Having spreads around 3 points for all these teams is terrible, and they are all pretty embarrassing losses for an NCAA tournament team.
the supposed 'elite' teams in the Big 12 were never more than 10-point favorites at TT this year. Okla, Baylor, Okla St, WVU, Texas, Iowa St were all mostly within a range of 6 to 9 point favorites on the road.
long beach was a legitimate top 100 team all season until recently (rumored locker room strife has led to their downfall). when you put them on their home court, it's the equivalent of beating a top-50 opponent. long beach played xavier, ucla, texas, san diego state, st john's in non con - all are tourney teams.
the spreads would have been the following in games played at lbsu:
xavier -4.5
ucla -3.5
sdsu -4.5
texas -8.5
st john's -3
byu -7.5
losing to a 100-level team at home is bad. losing to them on the road isn't really the disgrace that some are making it out to be. long beach took BYU to the wire on the road; they beat Xavier on neutral; they lost at San Diego St by 1. k-state was in an unreal bad spot with that game being played prior to the maui tourney, but even absent of that, it was far from a sure or easy win.
