Nuggets Lakers simply because it determines the Thunder v Nuggets/Lakers match-up in the playoffs. The whole triangle is really good right now.
Cavaliers vs the field. You can really get anything any night. They're a good squad.
Thunder Lakers is fun even more so due to the coaching match up. I think it's 1v2 coaches in the league right now, maybe tied with Kenny on the Cavs.
I'm not high on the Celtics this year. I think they will only win the one with that squad, and Kenny/Mark/JJ will out coach him from here on out.
