Defensive end Jadeveon Clowney told Yahoo! Sports that's what Luck will have to do if he was selected by Houston with the No. 1 overall pick.
The Texans picked Clowney to team with fellow defensive end J.J. Watt to torment quarterbacks for years to come.
The Colts were the only team in the AFC South not to have a first-round pick Thursday.
Jacksonville, which had the No. 3 pick, didn't follow Houston's footsteps by selecting a defensive player to help them against the Colts. The Jaguars were on the offensive by selecting a quarterback. It wasn't Johnny Manziel, though. They surprised many by selecting quarterback Blake Bortles. Bortles will have a chance to compete for the starting quarterback spot next season with Chad Henne. The Jaguars hope Bortles turns out better than Blaine Gabbert, the 10th pick in 2011.
