It's easier in the NBA because the teams are so much smaller and one guy makes that much more of a difference.
That said, it would be a crazy dynamic if AD went to the Rams and either on his own or with other big $ vets decided to pool some money to sign someone on a short term deal to try to create a super team.
Oh, and I just thought of a way for Kroenke to totally funnel a TON of money to AD.
Have AD start a construction company. He can build Habitat for Humanity homes and funnel his charity monies through that. Then, have Kroenke WAY overpay to buy his construction company.
The minute he's retired, the private entities could consummate a deal in which Kroenke pays $100M for a company that's worth less than $1M.
And nothing would be illegal about it because it's a private transaction outside of football with a former player.
Now, I know there are regs about not outright paying former players...like paying a former player $10M/yr to be a quality control coach, but nothing says a real estate dev can't buy construction companies.
I wouldn't do this. Kroenke...don't do this.
