TCU's opponents have consistently had a much stronger win / loss record before playing us, and a worse record after playing us. On the flip side, Baylor's opponents haven't had a noticeably worse record after playing them. I have no idea what this means, if anything, and it could all be some kind of cosmic coincidence. That said, I do have the sense that TCU has the ability to beat teams twice, meaning they play worse the week after playing us.
Here are the stats:
First, on an overall scale:
Win/Loss record of TCU's conference opponents, before playing TCU: 30-8 (.789).
Win/Loss record of TCU's conference opponents, after playing TCU: 4-7 (.364).
On the flip side:
Win/Loss record of BU's conference opponents, before playing BU: 19-13 (.594).
Win/Loss record of BU's conference opponents, after playing BU: 10-8 (.556).
Then, on a more immediate scale:
Win/Loss record of TCU's conference opponents, immediately after playing TCU: 1-4 (.200).
OU beat Texas by 5
BU lost to WVU by 14
OSU lost to WVU by 24
Texas Tech lost to Texas by 21
West Virginia lost to Texas by 17
Win/Loss record of BU's conference opponents, immediately after playing BU: 3-2 (.600)..
Iowa State lost to OSU by 17
Texas lost to OU by 5
TCU beat OSU by 36
West Virginia beat OSU by 24
Kansas beat Iowa State by 20
Again, I have no idea if this means anything, but the W/L record coming into the games certainly reflects the gauntlet TCU just ran. I also believe that the immediate results reflect the comparative toll that playing against TCU has taken on opposing teams this season.
