We had a drive (with our 3rd string QB no less) lasting 11:40, starting at the YSU14, and running 22 plays, driving 86 yards for a TD. In case you are wondering like I was if that was the longest drive in college FB history, it wasn't, but it wasn't far off.
From Wikipedia:
The 2004 Emerald Bowl was a post-season college football bowl game between the New Mexico Lobos and the Navy Midshipmen on December 30, 2004 at SBC Park in San Francisco, California, United States. The game, which Navy won with a final score of 34–19, was highlighted by a 26-play drive from the Midshipmen that took up almost 15 minutes of game time and set the record for the longest drive in a National Collegiate Athletic Association (NCAA) college football game.
In the NFL, the longest drive (by time) was by the Tennessee Oilers on 11/27/1997 against the Dallas Cowboys - the drive lasted 13:27, and they ran 21 plays to go 90 yards, and the drive resulted in a FG. There were two other drives in NFL history lasting 22 plays, but consumed less time.
