"I've had conversations with Jon in the past. I don't think it's outside the realm of possibilities," Gannon said of Gruden's possible return to the Raiders.
Gruden "still has the desire to get back and [coach] at some point," Gannon said.
"I don't know when. I don't know where, but I know this, that he had two bad experiences as a head coach with some owners that he just had a tough time with," Gannon said. "And you know I think it's pretty clear that he didn't necessarily see eye to eye with [Raider's General Manager Al] Davis and I think he was really disappointed at what happened with the Glazers [In Tampa Bay]... and I think he wants to go somewhere where he's got an owner that's not gonna, you know, try and pick the roster and try and call the plays, and just a guy that he can just come in and work for and hire a staff and get the thing turned around."
