Thought this was some pretty interesting stuff.
There's a game in '68 against NC where USC trailed 27-3 in the 4th and scored 29 pts in 10 minutes.
Another one against UVA in '52 where they scored 21 in 1:45.
I figured Mizzou was about the best 4th Qtr comeback, but I guess not. It has been a long time since one like that though.
