The Detroit Lions and Darius Slay agreed to a 4 year contract extension worth just over $50 million with $23 million guaranteed. An extension was expected for Slay as he is due to become a free agent next season. The move was a must for a team that desperately needs to keep its talented young players. With the retirement of Calvin Johnson, the Lions now have plenty of salary cap room to make moves like this to extend players who will be due larger contracts. Slay, who performed among the best in the league at his position last season, changed agents in the offseason and made it known that he wanted a contract extension to remain with the Lions beyond 2016. Today, he got his wish to remain a corner stone of the Detroit Lions secondary.
