Mavs have some tough games coming up.
I'll predict they have to finish 2-3 games under 500 for the year.
2 under .500 would require a 7-11 finish. Possible, given their schedule, but that's likely a lower bound. As a general note on math, unless a game is cancelled, you can never finish an odd number of games away from .500, since there are an even number of games. So finishing 3 under .500 is borderline impossible.
In order for the Jazz to catch Dallas, the Jazz would need to go 11-8 of the Mavs go 7-11, and win the head-to-head meeting. Considering Utah has 2 left against the Warriors, and one each against the Spurs, Clippers, and Cavs, they don't have a lot of margin for error in the rest of their games. Given that they're a below .500 team for the season, it's hard to see this team going 11-3 against teams not in the top 5 of the league. Not impossible, but as I said earlier, I'm not getting my hopes up. I think we have a better chance of getting a top 3 pick from Brookyln.
