NEW ORLEANS -- Ed Donatell sure didn't sound Tuesday like an assistant coach ready to leave his post as 49ers' secondary coach to become the Philadelphia Eagles defensive coordinator, a move that one Philadelphia broadcaster projected last week.

Donatell is in his second season on coach Jim Harbaugh's staff. He confirmed that he would like, at some point, return to a defensive coordinator role, having previously served in that capacity for the Green Bay Packers and Atlanta Falcons.

"I definitely aspire to do that, but I also know a good thing," Donatell said Tuesday during the 49ers' Media Day session for Super Bowl XLVII. "It's set up so we can have some nice years here."

Donatell is under contract with the 49ers for next season, so they could block any potential interest other teams might have in him. Donatell said he's had no official contact with the Eagles, who've hired Chip Kelly as their coach.

"Jim Harbaugh has created such a great working environment that nobody is in any hurry to get out of here," Donatell said. "There's no question this stuff will be putting out guys (as head coaches) in the next couple years, guys like Greg Roman, Vic Fangio, Brad Seely, Jim Tomsula, and on and on. We've got great assistants."

The Eagles reportedly interviewed former 49ers defensive coordinator Billy Davis for that same role last Sunday. Philadelphia broadcaster Howard Eskin tweeted last week that Donatell was expected to fill that Eagles job.
