A showdown between first-term San Antonio Mayor Gina Ortiz Jones and longtime City Manager Erik Walsh appears to be shaping up as City Council prepares to meet Thursday to discuss plans for a new Spurs arena. Despite Walsh finalizing a non-binding term sheet with Spurs Sports & Entertainment (SS&E) on Sunday, Jones is still calling for a strategic pause in talks with the team along with a second economic impact study on Project Marvel, the $4 billion sports and entertainment district that would be anchored by the proposed NBA arena. With Jones and a many on council unable — or unwilling — to find common ground, Thursday’s meeting could be shaping up to one for the books.
