The 5 best free agent signings in Detroit Lions history
4. MLB Stephen Tulloch
A fourth-round pick by the Tennessee Titans in 2006, Tulloch signed with the Lions in 2011. Detroit ended a playoff drought that dated back to 1999 ended that season, with Tulloch as an upgrade at middle linebacker.
Tulloch started every game in four of his five seasons in Detroit, with over 100 total tackles (and more than 70 solo tackles) in all four and multiple sacks three times in the five seasons.
3. S Glover Quin
Quin was a leader on and off the field upon arrival in Detroit. Oh, and he was also a pretty productive player. He never missed a game in six seasons as a Lion, with a Pro Bowl nod in 2014 as he also led the league by himself with seven receptions. After a down season in 2018, he was cut by then-general manager Bob Quinn. He later announced his retirement in the summer of 2019.
