The Texans need to find a solution at quarterback though after veteran Matt Schaub had a terrible season and was benched after six games. He was replaced by Case Keenum, but the former record-setter at the University of Houston proved he wasn't the answer, either.
Houston has the top overall draft pick and could use it on a one of a trio of talented signal-callers who could be available. Louisville's Teddy Bridgewater, 2012 Heisman Trophy winner Johnny Manziel of Texas A&M, and Fresno State's Derek Carr, younger brother of Houston's first-ever draft pick, David Carr, are the top-rated quarterbacks expected to be in the draft.
Defensive coordinator Wade Phillips served as interim coach for the last three games and reportedly interviewed for the job along with former Chicago Bears coach Lovie Smith. But Houston went with O'Brien instead, going with a first-time NFL head coach for the second time in its short history.
Many Penn State players took to Twitter on Tuesday night to congratulate O'Brien on his new job. Cornerback Stephon Morris tweeted: "Couldn't be happy for coach O'B. Chasing his dream, he deserves it. Pls PSU don't bash him. He's done a lot for us & he deserve our support."
