Without a baseline, not to mention temps, you're not really refuting anything.November games against southern teams:
2016: L OU
2016: W TTU
2015: L OSU
2014:L OU
2014: L TTU
2013: L TCU
2012: L OU
2011: W OSU
2010: None
2009: L OSU
2-7 basically suggests we have no "cold weather" advantage. We pulled a huge upset once and beat a very average Tech team last year. We might as well hope for nice weather because the cold appears to not matter against teams that are better than we are (exception being 2011 OSU).
Obviously the talent and coaching matters more than ambient temperature. No one has claimed otherwise.
