The NFL probably has the most turnover from year to year of all the major American professional sports leagues. Lots of rosters are filled with short term contracts, and the ones that look like longer term pacts are usually shorter deals in disguise. Teams are often forced to let players go more because of cap ramifications than on field ability, so these players often quickly find new homes.
The Panthers have popped up a lot over the offseason with all of the signings they’ve made, and it’s easy to lose track of who has left and where they’ve gone.
