It's pretty common knowledge that to win in the playoffs you need a bench.
That teams who rely on their starters alone don't do so well.
Clippers, Portland(aldridge & Lillard eras), Bulls(Drose era), Thunder, Bucks, Memphis.
Where teams that have a bench, or bench players who can be relied on to score do well.
Rockets, GSW, Spurs(Duncan era), Lakers(Shaq & Kobe), etc.
Hell you look @ prime LBJ/Wade/Bosh. Miller and old man Ray Allen played huge scoring roles for those teams in the playoffs on the way to the ring.
History has shown that going into the playoffs where teams rely on their starters too much for scoring. Those teams fail, where teams with depth succeed.
Now it's an entirely different argument on if I think Kanter/Layman/Curry/Turner/Collins/Hood provide that punch.
I will say that Portland hasn't had players like Kanter/Hood in quite some time. They still don't move my needle.
