I think they finish around 48-49 wins. There are just so many Playoff teams they go up against the rest of the way. Also, in 20 games, the Blazers have shown that they could easily lose a game they should win and also win some games they aren't favored in so tough to pin down.
Thunder x2
Rockets x2

7 games at home, 6 on the road against tough teams. It's pretty easy to find 4-5 losses on the road and 3-4 losses at home. They have been playing better at home of late but not against this time of competition on such a regular basis. That would also require them to go 7-0 against everyone else which should be doable but they almost lost to PHX the other night except Dame turned into Superman.
