Davis split ways with the Cardinals in 2006, and in 2007, he signed with the Dallas Cowboys for a seven year, $49.6 million contract. Once he moved to the Dallas, he also got back to the guard position. 2007 also saw his excellent game as he made the Pro Bowl for the first time in his career. What’s more, he was the one to make the All-Pro second team along with ex-teammate Flozell Adams. But on the other hand, Davis was the 5th most penalized player in the NFL with 42. The Cowboys had to release him in July 2011, due to his declining play. Spending 2011 with the Detroit Lions and the following year with the San Francisco 49ers, he eventually became a free agent. Off the field, Leonard Davis is also the bassist in the heavy metal band Free Reign.
