According to ESPN, the Cowboys' interview today with Miami Dolphins quarterbacks coach Jason Garrett could have an impact on Dallas' decision to go after San Francisco offensive coordinator Norv Turner.

From ESPN:
The Cowboys' plan for replacing Parcells at this point is to determine whether Garrett as offensive coordinator can call plays, develop the offensive scheme and manage the offensive coaching staff and the players -- particularly Terrell Owens. If it is determined that Garrett, who has never called plays, can handle that much responsibility, then the Cowboys are expected to pursue San Diego defensive coordinator Wade Phillips to replace Parcells. If Jones decides that Garrett is not quite ready for that role, he would be hired as offensive coordinator and then paired with Norv Turner, who can handle the overall offense.
