La Russa was Weiss' first Major League manager, with the Athletics, and since taking the Rockies job Weiss has talked strategy with La Russa.
As for the decision of Girardi -- once a teammate of Weiss with the Rockies -- Weiss figured it was not his business to comment or analyze.
"I have enough trouble managing my own team," Weiss said. "I'll let Joe manage those guys. It's the first time I've seen it as far as a manager, but I've seen it plenty of times in the past. Tony La Russa did it a lot."
