I mean he just has a different mindset now
Unless he has different knees now, his mindset won't matter.
Seriously though, if he and Wade can stay healthy and play well, it will be another cakewalk to the finals for the Cavs. They still don't beat the Warriors though.
If they can't stay healthy and/or don't play well, the Cavs may not make it out of the east. Especially if they struggle to fit IT in.
