Let's not get carried away - he wasn't even the MVP of the finals last year, where he averaged 26/5/6 on 44% shooting and 38% on 3s. Excellent output, but not in the realm of "dominant." And he was shut down in one or two games, IIRC.
In the post season last year, Curry averaged 28/5/6 on 46% and 42% from 3. Again, excellent, but not unstoppable.
In 95/96, for example, in the playoffs Jordan went for 30/7/4 on 51% from 2 and 43% from 3. That wasn't his best playoff year.
That comparison doesn't even take into account what an awesome defender Jordan was.
Point is, let's not get carried away - he's an awesome shooter who has the greatest ever combination of shot speed and accuracy. That singular skill opens up a lot of other facets of his game, because defenders are obligated to close guard him. How much better can he be? Hard to tell. As long as his lightning quick shot is falling, his ceiling seems very, very high.
