Since they obviously would have a lot of games against each other, I don't think every team behind us can play .600, but let's see where that goes (rounding everybody up)...
1 (Denver)
2 (Memphis)
t3 Mavs (.615): 46-36
t3 Suns (.615): 46-36
t3 Clippers (.625): 46-36
t3 Lakers (.778): 46-36
t7 Kings (.500): 45-37
t7 Pelicans (.615): 45-37
t7 Wolves (.625): 45-37
t7 Warriors (.630): 45-37
11 Blazers (.630): 44-38
Jazz Tank, Thunder are the team that loses to let all these teams be way over .500?
So, in that scenario where we go exactly .500 and 8 teams in the WC go on that absolute tear...we're in a 4-way tie for the play-in. Of course, if you round everybody DOWN one game, we're in a 5-way tie for third (one team would have to do the play-in).
But looking at these numbers, I'd guess that if we go .500 the rest of the way, we make the playoffs outright and avoid the play-in, and it might be good enough for the 4 or 5 seed. And juuuust maybe the 3 seed, if nobody really shoots up the ranks.
Edit: Also, the 10th place position in the conference with 45 wins (a .549 record)? That's almost unthinkable! The Hornets last year were at .524 in the 10-seed, but the list of 10 seeds going backwards for 10 years...
.415 .524 .458 .458 .466 .347 .451 .476 .512 .439 .415 .451 .402 .500 .476 .451 .488 .402 .500 .415
That's an average of .452, which translates to 37 wins. Things may be a bit more competitive (and a bit more balanced) in the WC this year, but 41 is a better bet for the threshold to make the play-in than 45, I would think.
