Sorry, I grew up in St. Louis, but I do not buy the narrative that Kroenke was a cynical manipulator. There are some other facts which the STL sports writers have hardly acknowledged.
The state/city sports authority which contracted with the Rams to come to St Louis and controlled the Rams' stadium refused to honor their contractual commitment to upgrade the exisitng dome to top tier status (by 2005, I believe). The Rams (with SK as minority owner) gave them several more years to do so. Same result. The city pushed the Rams into arbitration, seeking to have Rams pay for stadium upgrades which the contract did not require, and LOST. They then refused to honor the arbitration-- which would have required them to honor the contract. (In fact, they had other priorities for the stadium, such as conventions.)
It was at that point in time, not before, that Kroenke began looking for land in LA. Only after the LA project had started moving forward did the St Louis politicians decide to try to come up with an alternative stadium, which they would have owned, requiring the Rams (again) to be a tenant in a shared stadium (with soccer.) No one in their right mind would have continued to deal with these folks by entering into a new deal, again, on their terms in their stadium. Certainly no one with a contractual right to leave and a willingness to spend their own money instead of public funds.
As for blasting the city with fake biased studies, I read the Rams submission to the NFL. It simply noted other existing independent studies pointing out that the St Louis regional economic market was not looking all that great for future growth-- something obvious from the lack of support to upgrade the stadium and many other factors.
Don't mean to be contentious, but I am tired of one sided versions of this stuff. I understand the feeling when the Rams left, but anyone angry about it should consider reviewing the actions of the Regional Sports Authority for the decade before the team left.
