At 6'3" and 211 pounds, Houston has a ton of speed for a linebacker. He can do a lot of different things on the second level, but his best fit is a 4-3 defense.
While having him rush the passer as an outside linebacker in a 3-4 scheme could work, Houston is at his best as a "Mike" linebacker in a 4-3 alignment. He also can play both outside linebacker positions in a 4-3 scheme due to his quickness and ability to factor in coverage.
Houston told the following to USCFootball.com Recruiting (subscription required) on June 7:
"UCLA wants to keep me as an Anthony Barr type player on the outside. They want me to rush the quarterback, drop into coverage and go man with the running back. At USC, depending on what I do on the outside, they want to move me inside and make me more of a leader on the defense.
