He put up astronomical numbers at Houston, throwing for 155 touchdowns, 19,217 yards and 1,546 completions—all of which are NCAA records.
Keenum also developed a reputation as a winner in college. With him as QB, the Cougars posted a winning record every year. Last season, he led them to 13 wins, the most for a single season in program history.
Unfortunately for Keenum, that success will not continue in the NFL. He is not the sleeper that many want him to be.
Keenum just doesn't have the size of a prototypical QB. He is only 6'1". It's true that success can be had as a "short QB," but it is unlikely in his case.
From purely a talent standpoint, Keenum just doesn't match up with other NFL QBs. There were many questions about his arm strength heading into the combine, and Keenum fell flat on his face.
Per Russ Lande of Sporting News:
NFL teams understand the timing between quarterbacks and receivers is challenge because of a lack familiarity at the Combine, but that was far from Keenum’s biggest issue. Too often his passes would dip before getting to the target. Receivers often had to slow up and wait for the ball.
We have seen QBs in the past, who have put up incredible numbers at a program that plays lesser competition, be useless in the NFL.
Remember Colt Brennan?
The former Hawaii quarterback threw for 14,193 yards, 131 touchdowns and posted a completion percentage of 70.4. Brennan was drafted in the sixth round of the 2008 NFL draft.
He is no longer in the league and left it without throwing one single pass.
I wouldn't have an issue drafting Keenum and seeing if he could do what Brennan couldn't. He could potentially find his way as a decent backup QB. After all, he was graded highly on his intangibles and decision-making, which does mean something.
However, those who think Keenum will shock his doubters and become a productive starter some day are mistaken.
