A lot went into the toilet when University of Houston star quarterback Case Keenum crumbled to the Rose Bowl Stadium turf with a shredded knee. At that time, in September 2010, the Abilene-born athlete had put his name in the Heisman Trophy race, led a long-comatose program (and Houston's sports scene) out of infamy and placed the Cougars among the potential BCS busters. Then it all went poof when he tore his anterior cruciate ligament on the road against UCLA. However, Keenum — who was granted a sixth-year-eligibility waiver by the NCAA in January — has one last shot to return to greatness after enduring nearly a year of arduous rehabilitation and therapy. At press time, the Cougars will have completed nearly a third of the 2011 regular season, which means that the 23-year-old, barring injury, has had four games to prove himself. Stay tuned.
