8-12 sounds incredibly pessimistic.
I'd go for something like 14-6.
They been losing games to Lakers, Clippers, Bucks, Bulls, Raptors and Blazers like nothing
It's more like realism than pessimism.
Ebbs and flows. That's the worst stretch of the season. Unlikely to have great predictive value. It's akin to extrapolate the team was going to win 90% of the games for the rest of the season at the end of a 9-1 streak. Recency bias.
One game vs a team with a better avg point differential: @GSW.
Another 4 games vs teams with better records: vs DEN (only elite at home; 15/14 away record), @PHI (good matchup for Boston), two games vs the Pacers (weaker without Oladipo).
Another game vs a team with elite talent (Houston).
So a relatively soft schedule. Lots of late games vs teams that will be fighting for playoff position, as noted, is the most troubling fact.
