Univ. of Houston's Keenum has finished his college career after 6 years
I heard this on ESPN and had to look it up. He has been there since 2006.

2006 season
Keenum began his college career at the University of Houston during the 2006 season. During his freshman season, decorated senior Kevin Kolb held the starting quarterback position for the Cougars, leading the coaching staff to redshirt Keenum for the season. The 2006 Cougars won the Conference USA championship, and Kolb was drafted by the NFL's Philadelphia Eagles.
2010 season
Keenum was in a position to challenge more than one major NCAA division one passing record at the start of the 2010 season, including career passing yards and touchdowns. However, after throwing for a total of 636 passing yards and three touchdowns in three games, Keenum tore his ACL during the Cougars' third game of the season against UCLA. The injury ended Keenum's season and Houston would finish 5-7.[4]
---He got a medical redshirt
http://en.wikipedia.org/wiki/Case_Keenum
Almost immediately, Case Keenum applied to the NCAA for a medical redshirt which would grant him an unusual sixth season of eligibility. Keenum had endured a shoulder injury in his senior season at Abilene Wylie, preventing him from being able to compete in his freshman season at Houston and prompting the NCAA to issue him his first medical redshirt.
Keenum's appeal to the NCAA was not unprecedented, but typically a sixth year of eligibility is not granted without serious consideration by college sports' governing body.
