"I don't think they're sold on Clowney to fit in the '34' defense," Casserly said.
Clowney (6-foot-5, 266 pounds) was a defensive end at South Carolina and rarely dropped into coverage; while his main emphasis in the 3-4 obviously would be to rush the passer, he still would occasionally be asked to drop into coverage. Mack was a 3-4 linebacker in college and "is a better fit in the '34' than Clowney," Casserly said.
If Houston does find a trade partner, "I think Khalil Mack is the guy that they've penciled in or one of the quarterbacks, depending upon where they go farther back," Casserly said.
Houston needs to come out of the draft with a quarterback, but when the Texans grab the quarterback is the second-biggest question surrounding the team. The first, of course, is what they do with the top pick.
