This past weekend we had 9 games where a P5 team played another P5 team on the road. (technically UNC/USC and LSU/FSU were neutral site games)
So here are the results from worst result to best in terms of win margin
UVA lost to Tenn by 36 = 49-13
WVU lost to PSU by 23 = 38-15
Clemson lost to Duke by 21 = 28-7
NW lost to Rutgers by 17 = 24-7
Florida lost to Utah by 13 = 24-11
Neb lost to Minn by 3 = 13-10
Col beat TCU by 3 = 45-42
Louis beat Ga Tech by 5 = 39-34
OSU beat Ind by 20 = 23-3
That's a 3-6 record for the road team
Average points scored by road team 18.9, heavily skewed by the Col and Louis games, otherwise the other 7 were only 12.2
Average pts for home team = 28.3, heavily skewed by the OSU game, otherwise it was 31.5
Just food for thought when thinking about say how OSU did vs other "somewhat similar" match ups.
