When former Detroit Lions running back Kerryon Johnson, now with the Philadelphia Eagles, made a comment on Twitter this week that he hadn't laughed in practice for years, there's little mystery to what he meant.
Whether Lions players liked his style or not, few had fun practicing and playing for former coach Matt Patricia. The weight of that burden being lifted was also apparent in the laughter of Detroit safety Tracy Walker, who virtually met with the local media for the first time this offseason on Thursday.
On the field, Walker hit a wall last year. The up-and-coming talent labored through a role change in his third season.
