"As early as last week, though, whispers of a roadblock to a potential deal began cropping up in local media. “There are rumors,” said Frank Cusumano on his radio show, “that Dexter Fowler does not want to play for Mike Matheny.” Bernie Miklasz expressed a similar thought. Derrick Goold and Ben Hochman spent a good chunk of the latest Best Podcast in Baseball seeming to acknowledge the “grumblings” and things “in the wind” with regard to Fowler and alluding to unspecified “aspects” of the Cardinals “culture” that might not be a fit for certain players. Cusumano implied again this morning that Fowler is reluctant to sign with the Cardinals, albeit this time without mentioning Matheny."
Supposedly Matheny is very serious, the culture is serious, no fun allowed in the clubhouse, religious ect. Complete opposite to the Cubs.
