They can claim whatever they want, but there was no reason that Rock shouldn't have left Wrestlemania 2000 with the belt. Instead, they gave him the title at Backlash two months later only for him to drop it again at Judgement Day 2000 a month after that.
He should have carried and then dropped it at Judgement Day if they wanted to get it on HHH so badly (who, at the time, still wasn't completely being bought into by fans.) I don't believe any other of Vince's top guys would have gotten some of the bizarre losses that Rock endured. No one who made Vince that sort of money was ever taken for granted in that manner.
