Jazz will have to win more games than phoenix since they have the tie-breaker and both have 31 wins now. Phoenix has 6 games left, 5 at home. Jazz have 5 games left 4 at home, one of which is against Phoenix. If Phoenix wins 3 of 6, Jazz have to go 4 of 5 to win the tie breaker. Phoenix does have a tough schedule though with SA, Den, LAC, OKC and Portland as the 5 home games.
Houston has 1 game on us, but we have the tie breaker, so we have to win one more game than them as well. They have 6 games left, but only 3 are at home though, and they have lost 3 in a row. They do, however, play NO twice and GS once(Hopefully this one is a loss somehow).
Keep in mind that we have to pass both of them, so the chance of both of them dropping enough games, and Utah winning enough is pretty low. Denver is 2 wins ahead so they will be even harder to catch, even though they have a tough schedule (they would have to end 2-4 with Jazz being 4-1).
I am hoping they all stay ahead and Milwaukee wins enough to pass. 12 sounds a lot better than 14 to me

Heck, even Portland could pass us if they win both the games against us. (not saying I want the Jazz to try to lose though)
