Miller, 22, joined the Bucs as a third-round pick (110th overall) in the 2009 NFL Draft. He played collegiately at Texas.
The 6-foot-1, 310-pound Miller started 19 of the 49 games he played at Texas. He recorded 5.5 sacks, 28 quarterback pressures and 11 tackles for a loss as a captain in his senior season.
Miller's impressive strength and offseason helped him get drafted by the Bucs, but he carries a chip on his shoulder heading into training camp because he believes he should have been drafted in the first round, not the third.
The Bucs expect Miller to compete with defensive tackles Ryan Sims, Chris Hovan, Dre Moore and Greg Peterson, among others, for playing time in training camp, which the team reports to on July 31.
Tampa Bay has just one draft pick — first-round quarterback Josh Freeman — unsigned from its 2009 NFL Draft class.
