Kroenke typically invests little to nothing in the playing side of his sports teams and many of his teams Arsenal included have suffered since his take over. The move to LA is being part financed by the city if what I read is right. He stands to make far more in revenues from moving the team to LA so it makes business sense. Investing more money than is needed to make top 4 doesn't offer much extra revenue in comparison to the business cost.
Being an LA native, I can tell you that you're correct and incorrect here.
You are incorrect regarding Kroenke's move being financed by the cith of Los Angeles. The city of Los Angeles didn't pay a dime to get the Rams. Nor are the city of Los Angeles (or the city of Inglewood, where the new stadium will be located) giving money to Kroenke for his new stadium. The NFL itself is helping out a bit with the stadium and there might be a few tax breaks for it from Inglewood. But the majority of the money itself is coming out of Kroenke's own pockets.
As a matter of fact, the last
publically financed stadium in Los Angeles was the old Sports Arena, built in 1960. Every other arena built in LA (Dodger Stadium, The Forum, Staples Center, Galen Center, Pauley Pavillion) has been built either entirely with private money or, as was the case with Staples Center, a combination of private money plus a loan from the city which had to be paid back in relatively short order and with interest.
However, despite the large fine he had to pay for relocating his team from St. Louis to Los Angeles, you are correct that Kroenke stands to make far more revenues in LA than in St. Louis. The value of the Rams nearly doubled just from the move alone.
Moreover, there is no reason for Kroenke to "invest" in the Rams because the operating costs are already taken care of ahead of time. Operating costs in the NFL are controlled. There is a salary cap and player wages are covered from TV contract money distribution + league-wide revenue sharing. So before a ticket is sold, the team is going to break even at the very least. No team in the NFL loses money because of this setup.
This is most definitely different from Arsenal where he actually should be investing in the team.
And now back to Messi talk.
