Krejci's always been a good playoff performer. I don't think this changes his value too much, to be honest. But I've always considered him a 70ish point forward, despite his numbers from the past year not supporting that.
That said, if you can capitalize on his playoff performance and trade him to someone who thinks he is an 80+ pt player, you should jump all over that.
The thing about Krejci is that he is an underrated passer. If he plays with a shooter, his point totals will increase. But he won't score a lot on his own, he won't shoot a lot, and his PIMs won't help you either.
