Houston Texans CB Aaron Colvin was limited to 10 games, two starts, 29 tackles and one pass defensed due to an ankle injury after signing a four-year, $34 million contract that included $18 million guaranteed last offseason. However, he has impressed the coaching staff so far this offseason.’He’s had a good offseason. He’s been here every day, he’s worked hard. I think he’s definitely in that group of players that have improved, which is a big group. But there’s definitely been improvement because he’s been out there every day. He’s been healthy, he’s been working. He’s a hard worker. He definitely takes a good professional approach to every day,’ head coach Bill O’Brien told the Houston Chronicle.
