But he said there's one person that could ultimately help him with the decision.
"If Anquan [Boldin] tells me he's coming back, that will make my decision easier," Warner said.
And Boldin absolutely wants to see Warner in a Cards uniform next year.
"You definitely want to see a guy like him come back because I feel like he's got a lot left in the tank," Boldin said. "He's a guy that's playing at the top of his career. He's playing lights out, so you definitely want a guy like that to return."
Warner said he has no time frame for a decision. All he's focused on now is his family and life outside the NFL.
Warner played just five snaps for the NFC in the opening series and threw just two passes, completing an 8-yarder to teammate Larry Fitzgerald, who scored twice and led the NFC to a 30-21 victory to earn MVP honors.
Warner, who turns 38 in June, didn't get much work in the game, but did labor extremely hard this week. At every practice and every interview, Warner was repeatedly asked whether he would continue playing.
The Cardinals have already lost offensive coordinator Todd Haley, who last week was hired as coach of the Kansas City Chiefs.
Warner said Haley's departure would also factor into whether he returns.
When he's ready, Warner said he'll let the football world know.
"I'm glad we had the season that we did, and I enjoyed every minute of it, but I'm very much looking forward to the offseason," he said.
