The only way this makes sense is that they will probably rack up some pretty good sponsorship $$$$.
Apparently they have a heap of people looking to sponsor him/use him for their purposes.
Could probably offset his cost.

Maybe it’s a business deal instead of a football deal.
Chuck him in at CB, say Mr Bolt, just kick two shades of sh*t out of the ball.
Be interested to see how he goes actually haha. Gonna be funny
