MIA, IND and TOR doing very well are important to my competitive chances.

Other stuff with smaller differences too, of course.

Good weekend. Tonight was probably alright.

Still could be volatile. Rest might have some impact. Tanking might in a few cases.

This may or may not be the final regular-season "projection" from b-r.com
For some reason, their projections add up to just 80 games (W+L) for most teams, but 81 or 79 for a few.
Extrapolating all to 82 G, we get this:

Code: Select all

62.8   LAL      65.8   Mil
56.3   LAC      57.5   Tor

Well, nobody reminded me to get back on this project, and I had pretty much written off the rest of the season. But here we are again, the bubble hasn't burst as yet, and the re-season is winding down.
Basketball-Reference.com has gone commercial, so many search features are unavailable now. Yet they still have the Playoff Probabilities Report.

Lottery teams "project" to the (64 to 67 G) records they had as of mid March. "Bubble" teams project to anywhere between 71 and 75 games. I've extrapolated their projected (or current) Win% onto 82 games for this exercise.
While it looks as if the sum of all wins and losses should end up at 1059 of each, the avg Win% is a bit under .500, and the 82G projection averages 40.58 wins.

In our contest, everyone has improved with the bubble games, and Crow's lead is cut in half.

I've not looked into what 'play-in' means, or whether b-r.com is figuring that into their projections. Assume they will be counted as 'regular season' games rather than playoff??

Right now 8 east teams and 7 west teams have a 100% chance of making the playoffs. Then we have:
.546 Por
.179 Mem
.153 Phx
.122 SA
Not sure why Grizz are given the edge over the Suns. Same 33-39 record, Phx with 1.4 better SRS

I considered it a win at the interruption.

The score after the bubble is a bit affected by all the resting, but let's see what it shows.

Thanks for the reporting.

b-r.com has done a strange thing and projected an additional 7 game results onto all bubble teams but the Lakers and the 4 also-rans. It shouldn't matter, since I'm already scaling everyone up to 82.
