How is the fourth-best punter in NFL history not on an NFL roster?

This is my honest question to the masses. This kid is fourth all time in punting average in his career. He can easily play until he is 40, the kid is jacked up, looks like a WR. Yet, he is not on a roster. He went to XFL, led all punters there too. What else do you want? https://t.co/l18ZFt2VkW
