5 greatest one-hit wonder seasons in Detroit Lions history

3. DE James Hall (2004)

Hall signed with the Lions as an undrafted free agent out of the University of Michigan in 2000. He toiled fairly non-descriptly for his first four seasons, totaling 11.5 sacks, though he did start 30 games over the 2002 and 2003 campaigns.

Then in 2004, Hall exploded with 11.5 sacks (tied for sixth in the league), 10 tackles for loss and four forced fumbles (tied for seventh in the league). It's worth noting hesuffered a broken hand in the first game of that season,

Hall earned a contract extension from the Lions with that perfomance. Then he was traded to the St. Louis Rams in 2007. He had another out-of-nowhere boom season for them in 2010, with 10.5 sacks. He spent 2011 with the Rams, then his NFL career was over. He played 12 NFL seasons as an undrafted free agent when the average career for anyone (drafted or undrafted) is far shorter. So let's not overlook that accomplishment.

But over his other six seasons in Detroit specifically, Hall totaled 21.5 sacks with no more than five sacks in any of those. He had his big season in 2004, got a nice contract and was otherwise not a big producer even as he became a regular for the Lions.
