Houston quarterback Case Keenum broke almost ever major quarterbacking record during his college career, but the 2012 NFL Draft came and went without his name being called. Eleven quarterbacks came off the board during this year's draft and Keenum wasn't one of them. The reason is simple: he just doesn't have the natural physical gifts or talent to play in the NFL.

The 24-year-old signal-caller completed 69.4 percent of his collegiate attempts and set NCAA records for career passing yardage (19,217), total offense (20,114), touchdown passes (155), completions (1,546), touchdown passes (155) and 300-yard games (39) and was also the first player in NCAA history with three 5,000-yard seasons.

Despite those gaudy statistics, Keenum was a system quarterback at Houston who simply doesn't have the physical tools needed to succeed at the next level.

He measures in at 6'1" and 208 pounds, and has average speed for the position. While Keenum has a fairly quick release, his passes don't have much zip on them and he often floats his deep balls. He also has a bit of a sidearm release that will leave him open to getting passes tipped at the line.

Houston's offense hurt Keenum from a diagnostic perspective, as he never really had to make difficult reads in the team's shotgun spread attack. He rarely had to fit the ball into tight spaces, and that hid the fact that his arm strength and accuracy are just average.

Keenum is good in the pocket and can feel the rush coming, reacting accordingly. But he's not a mobile guy who can consistently get yards with his feet when things break down. He was able to do that occasionally against weak competition in Conference USA, but wouldn't have that ability at the next level in a pro-style offense.

Some people love Keenum, and he is an easy guy to root for. He's a great kid and is polished as a leader, but there is a reason he wasn't selected in the 2012 NFL Draft. He just simply doesn't have the skills necessary to be successful in the NFL.
