i asked about this yesterday. so i thought i'd post what i found with a very cursory search..
Teams playing at home on ESPN Thursday night college football games have an astounding .628 winning percentage against the spread over the last five years, according to BeyondTheBets.com.Overall, home teams went 49-29 ATS. But home underdogs did even better, posting a 22-12 record for a .642 mark. looks like the study was to start of 2011 season, so see if i can update by hand for last 2 seasons and the start of this season.
i gather friday night plays differently..... i'm in canada so i don't know this. are friday night games on ESPN too?... but i think they have different feel anyway. people are at high school games for most part anyway.
