Oh, it seems I may be mistaken about Hatcher:

Dallas Cowboys[edit]
Hatcher was drafted in the
3rd round (92nd overall) of the
2006 NFL Draft by the
Dallas Cowboys. His selection at the time was questioned because of his lack of production in college, but the team was high on his athletic ability and potential for their
3–4 defense.
As a
rookie, Hatcher played in 14 games, missing two with a sprained
ankle. For the season, he recorded 13 tackles, one for a loss and 2.5 sacks. In
2007, he played in all 16 games and recorded 35 tackles, three for losses and two sacks, while forcing one
fumble. In
2008, Hatcher recorded 36 tackles, one for a loss, one pass broken up and one sack. In
2009, he played in all 16 games and recorded 29 tackles, one sack and one pass breakup.
For the most part of his career with the Cowboys, Hatcher was a reserve player (his first start was in
2010) and seen as a disappointment, until he re-signed with the team in
2011 after not receiving much interest in the
free agent market. That season with the arrival of
defensive coordinator Rob Ryan, he established himself as one of the team starters at
defensive end, ahead of
Marcus Spears and improved his overall play, compiling a career high in tackles (36) and sacks (4.5).
Looks like he did see action during his rookie year. I thought he was more stashed though at first. And it states he was a reserve player for the most part, so that may be what I was thinking. It wasn't until Rob Ryan came along that he became a starter for us.
