The Detroit Lions invested a lot in the middle of their defensive line, drafting Ndamukong Suh No. 2 and Nick Fairley No. 13 in consecutive years, without much of a return. Suh chose to leave the Lions last year as a free agent, signing with the Miami Dolphins. The Lions let Fairley go, and he signed with the St. Louis Rams, lasting only one season with them before joining the New Orleans Saints this year.
