No, it is not. There is $140 mil. or something like that for injury guarantees but I am sure there are clauses like "no basketball, snow boarding, football etc. in off season" to safeguard the team.
Heck, the team might even have a life insurance policy worth half a billion on him (not sure if that is legal, insurance experts chime in).
There were some big issues taken with how that poll was conducted. This 2020 study found much different results:
On ESPN, they said that in a recent poll, 90% of native Americans did not find the name offensive. They considered it an honor of sorts. I didn't see the data, but since ESPN is usually on board with the left, it was surprising to hear them report that.
After a Google search, it appears to be true.
So is it more important to force a change that goes against the group involved than to let the majority rule?
I really don't care one way or another.
