I was trying to find last week's line for Florida v Florida State to use, and accidentally bumped into this, which I found interesting.

It gives the last 10 years of historical results in underdogs winning games outright, depending on the point spread. Some of them are pretty surprising to me, although you may not be so surprised.

There have been 5 outright winners in the last 10 years who were 30 point or more underdogs. Of course, it's a tiny percentage, but that's still pretty amazing, even though on average you just have one every two years.

For 13.5 point underdogs, surprisingly (to me), the underdog wins almost 20% of the time. I find that high, but that may just be me.

Overall, the correlation is pretty strong with the point spread. There have been 219 games where a team was a 1-point favorite. The record? 110-109.

Fascinating, or at least, I found it so.
