You are correct. On a prior thread there was a suggestion that Damar was a gazillionaire. Far from it, particularly given that the average NFL career is 3-4 yrs.Christian Eriksen was and is, one of the most celebrated and best remunerated players, in Europe. He probably earns as much in a couple of months, as Damar Hamlin does, in a year, to play a much less explosive sport.
The average draftee plays for perhaps four years, in the NFL. You would hope that Damar's agent is looking for alternative ways to turn his international celebrity, into a longer term career.
