I was a huge fan of Boston Celtics when there were Big 3 on the team. They have disappeared and now I'm a fan of Cleveland. But I'd like to say that I liked Celtics more than I do Cleveland now. In this situation, these sentences are possible to use? Or is there any difference between them?
I used to be a bigger fan of Boston Celtics than I am of Cleveland now.
I'm not as big a fan of Cleveland as I used to be of Boston Celtics.
