This is really going to go down to the wire regarding Houston, Utah, and L.A. (Warriors should finish in the playoffs at this point unless they really collapse.)
Lakers have a pretty average schedule. Basically even split home and away, against over .500 teams and under, 5 b2b's. Assuming that their current play is indicative of them turning a corner of some sort and they keep playing the same way, they'll likely get to 44 wins. I wouldn't be shocked to seem them revert and struggle to get to 41 though.
Rockets have an easier schedule than the Lakers, with 14 home and 10 away games, and just 10 games against teams over .500 (and 14 against under .500 teams), with 4 b2b's. I would expect them to improve on their current win percentage over the remaining games, meaning they will should finish with at least 44 wins, and probably 45 or 46. Predicting less than 44 wins for them I think is a mistake.
Jazz have 14 games at home, 12 on road. 14 games against >.500 teams, 12 against below .500 teams. 3 b2bs. An average difficulty schedule. Our schedule is not as easy as the Rockets, but easier than the Lakers. Assuming we go 14-12 on this stretch which is very reasonable, we end at 45-37. I would be really surprised if we end with less than 44 wins given our schedule. We project to finish with about the same record as Houston. Maybe one win better. Given our sched, I find it very unlikely we end up at 43 wins. That would be some serious underperforming.
What this means is that, given schedules, Houston and Utah project to about 45 wins each at this point. Basically, this means the Lakers need to really go on a tear to make the playoffs, or one of these two teams (or I guess the Warriors) has to really underperform in relation to their schedule. It's possible the Lakers go crazy and finish the season 19-6 or something, in which case they manage 47-35 which will almost certainly be enough to someone out. Other than that, it will be neck and neck with Houston, Utah, L.A. all around that 45 win mark. Or, just as likely, L.A. finishes around 41 wins and isn't really in the race for a spot.
