Hogan and the AWA title does seem like an obvious pick, but Hogan didn't want the title because of his deal with New Japan at the time. Verne Gagne had a deal with rival All Japan and wanted a percentage of Hogan's NJPW earnings, which Hogan refused. Hogan was going to accept Vince's offer whether he was AWA champion at the time or not. Vince would have insisted that Hogan not do any jobs on the way out (ie: drop the title) and Verne probably would have had a situation on his hands similar to that of the debacle with Stan Hansen in '86.
I tend to find myself amused when people talk about Montreal and Bret doing the right thing for business etc, yet during Vince's expansion in 1984, he didn't have any problem asking someone to simply walk out of a territory and if they had a belt, that would be a bonus. Same theory applies to the Monday Night Wars and WCW raiding Vince's talent. Somehow it was all unfair whenever the shoe was on the other foot.
