He could really like it, so can Kroenke, but I wouldn't read too much into favorite tweet because it's his job to encourage fans to spend money, regardless of the city. I think he probably does like it, because it does look nice, but I doubt it means anything about what Kroenke is thinking. Hard to imagine they would tip their hand like that.
What? That's not very accurate. Any LA plans were either owners making a show about exploring LA (Vikings, Colts, etc) which didn't have any stadium location/design plan, and thus would be leverage, or private investors making plans for a stadium (AEG, City of Industry, etc) that didn't have any team backing, thus would not be leverage. The difference between Inglewood (and Carson) is that it's a stadium and location WITH a team backing it. The difference between Carson and Inglewood is that Kroenke has actually bought the land and is going through everything to actually build.
