Based on strength of schedule, I'd have to place Utah in 8th right now. I hope I'm wrong, of course, but the Jazz have some very winnable home games coming up (Orlando, Detroit, New York, New Orleans, and Lakers). Utah has played well at home, with close come-from-ahead losses to playoff-caliber teams. Even the home games against Memphis, Dallas and Portland aren't automatic losses.
Lakers have a brutal schedule and Sacramento has the fewest number of games left against "tanking" teams. Detroit has almost twice as many away as home games remaining. Let's hope that 4-game lead over the Jazz holds up. As for Boston, they have fewer games against "elite" teams, but many against the next tier (including H/A series against Toronto, Chicago, Washington). Those teams are all fighting for playoff positioning and have been playing well.
