Childress discussed the topic during an interview on all-sports radio station KFAN in Minnesota last week when asked about the subject by a caller.
"We're always in a dialogue, the offensive staff and I, and that's not something I've completely excluded from my thinking right now," Childress said of the potential for a change. "But I think as we get a little bit closer (to the season) it will define itself."
The Vikings finished 6-10 in Childress' inaugural season and there was plenty of criticism for an offense that registered its lowest point total (282) since 1993.
If Childress did give up the play-calling, or more likely scaled back his involvement, the assignment could fall to offensive coordinator Darrell Bevell or quarterbacks coach Kevin Rogers.
Last season, marked Bevell's first as a coordinator at any level. Before joining the Vikings, Bevell had spent six seasons working as a member of the Green Bay Packers staff. His final three years with that team Bevell served as quarterbacks coach.
Rogers, meanwhile, has been in coaching for 32 years and was the offensive coordinator at Notre Dame from 1999 to 2001.
Rogers was courted by the University of Miami to be its offensive coordinator after this past season but decided to remain in Minnesota.
QUOTE TO NOTE: "I believe we were right in it. I know what offer we made, I know what offer he accepted. He probably accepted less to go there. He wanted to be in Philadelphia and you put your best foot forward. It's a little bit of a different free-agent process there with him switching agents in midstream. But he's where he wants to be. He's a good football player. You can't take anything away from him." — Vikings coach Brad Childress on his team's failure to sign free-agent receiver Kevin Curtis, who wound up taking a six-year contract with Philadelphia that is worth up to $32 million and reportedly included $9.5 million in guarantees.
