You can throw that stat up all day but unless Iowa plays MSU, NW plays OSU & Wisky plays Michigan, Nebby plays PSU, on down the line... those results are the true indicator.
Direct competition is the only unbiased metric we have to go on; some of the 'bottom feeders' of the West gave top teams in the East some very stiff competition - Purdue losing 24-21 to MSU, Minn losing 29-26 to Michigan (and if they had ANY semblance of clock management, would have won or tied that game).
I fully understand that the Michigans/OSUs/MichSts/PennSts have 'better recruiting classes', 'better historical performance', etc. etc.
But those are biases and perceptions, not relevant facts.
In 1984, a North Carolina men's BB team with four current or future NCAA Consensus All Americans played an Indiana team with only one 'name' player.
It was Sam Perkins, Brad Daugherty, Kenny Smith, Michael Jordan and others vs. Steve Alford, Mike Giomi, Uwe Blab, Daniel Dakich and Stew Robinson.
NO WAY could that Indiana team of 'nobodies' even stay on the same floor as 4 current/future NCAA Consensus AA's, 2 of which were future NBA All Stars, and one which was a future NBA MVP and all-time great.
No.freaking.way.
72-68 says otherwise...
