If two teams move to LA then there should be a 25,000 seat stadium they can use so it looks like a big crowd sellout. The NFL has capped its organic growth and has real problems with fan support in Jacksonville, Tampa Bay, and other sites. That is why they look lustfully at London, Mexico City, Tokyo etc but I don’t see that ever working. Maybe the NFL needs to downsize instead of upsize. As for Cleveland, Art Modell gave them a really raw deal, in part to settle his gambling debts as I have heard. Same with the old Baltimore Colts of Unitas fame. The effeminate media including the networks and ESPN are also degrading the NFL product. Many would turn it into touch football if they could.
It was a shame that Cleveland and Baltimore left. The league does a better job now of controlling the process, but they are not managing the LA market very well. Politics between the owners is dictating who gets to do what, instead of what is best for the product that the league tries to sell.
