No, he isn't.
As a matter of fact, teams are wondering why he allowed so many catches in front of him this season....he has dominant workout numbers, but he's just an above average CB.
Don't forget that Arkansas led the SEC (and they were among the nation's elite) in rushing the ball. They held the ball, so teams did not have an opportunity to get into their offenses. They also had a pretty good pass rush.
Don't mistake me....I love Arkansas. They're one of my favorite NCAA teams. But Houston is not a shut-down CB.
Yet....
The tools and potential are there....but the bust factor is also there.
