Elko doesn't seen likely because his team is 7-0 and A&M's pockets are as deep as PSU's pockets. Even if he did come it wouldn't be until mid January after a lot of portal kids have been scooped up.
Same is true for DeBoer. Why would he leave Alabama for PSU?
Drink is the 11th highest paid coach in the country and his contract goes through 2029. He's been a southern coach since high school and probably has limited connections in PA, MD, NJ area. Why would he want to inherit the PSU situation?
I think Saban made it pretty clear that he isn't coming and I don't think Meyer is interested in a complete rebuild.
I think our best bet is somebody like Hartline or Joe Brady. Both would see PSU as a move up and could be available before things fall apart much further.
