The possible hall of famer told Showtime's "Inside the NFL" that he tells any person that calls him not to touch Oakland before Davis is gone.
"Al Davis knows football -- it's just '60s and '70s football -- that's what it is," Sapp said. "(He) is the common equation. You take him out, put him at home watching film or whatever he is doing -- you have a functioning football organization. He's thinking that (wide receiver) Cliff Branch is outside and (quarterback Jim) Plunkett is dropping back and you can throw it 80 yards down the field -- deep ball, deep ball, deep ball. Oakland won't change for the better until Davis doesn't own the team anymore. Kiffin 'never got a fair chance.'"
Sapp retired after the 2007 season, his fourth in Oakland.
