that graph is lacking context IMO
to start with, the 14-15 team has almost no bearing on the current team. Only one starter remains from that team, and only 3 players are the same...and one doesn't play while the other is injured
the graph should be the 4 iterations of the current team, and even then, I'd question if much could be projected from it
in 16-17, Portland won 12 of their last 16 games, 9 of their last 12, and 3 of their last 4, & Dame-CJ-Harkless didn't play in the game they lost....still, the Blazers were swept in the 1st round. Yeah, it was the Warriors but they lost the games by an average of 18 points
the year before, they won 7 of their last 9 and won the 1st round but we all know the circumstances of that series against LAC
even last season which shows up on that graph, they did lose 4 of their last 5. But prior to that they went 17-3. That's 18-7 over their last 25 games and you'd sure think that was a significant indicator of how they were playing
