When you think about finding a hidden gem in free agency, the mind often conjures images of a former top-tier or Pro Bowl player. Someone no longer in his prime, joining your squad in his final years. But in the case of offensive guard Kyle Kosier, Dallas landed a player who would eventually start for six seasons for the Cowboys.

Kosier was a former seventh-round selection out of Arizona State back in 2002. Originally drafted by the San Francisco 49ers, the 6-foot-5, 305-pound guard would spend his first three seasons with the 49ers, racking up 29 starts in that span.

In 2005, the coach that originally drafted Kosier in San Francisco in Steve Mariucci was now the head coach of the Detroit Lions. Mariucci signed the restricted free agent to play in the Motor City and the 49ers refused to match.

Kosier would play one season with the Detroit Lions, starting in 11 games. But Mariucci didn’t finish the season as the Lions’ head coach, and the versatile lineman hit free agency the following year. Kosier would find his NFL-forever home in Dallas. During his six seasons with the Cowboys, he started a full 16-game season four times.
