When you get beat in big matches, you are not dominant.
Yes, he beats 99% of the tour, but Djokovic does the same.
He is almost 30, and he said that slams would be his priorities.
Sampras never had as dominant season as Fedalovic' 3-slam seasons or even 2-slam+4 masters season, but he had four 2-slam seasons with 2 averaged masters therein.
So, it is all about slams now for Murray and I think that majority of his fans would rather see him as 2017 y.e. no.2 with two slams + zero masters than y.e. no.1 with one slam + four masters again.
