When the Celtics acquired Kristaps Porzingis and Jrue Holiday, the consensus was that Brad Stevens deliberately constructed a top-heavy roster and would fill in the missing pieces from there.
The star power was obvious, but depth was a legitimate concern – at least to the public. In hindsight, perhaps Stevens knew something others didn't at the time.
As the season has progressed, the Celtics reserves have turned that doubt into faith among fans with their steady production. The top-six is obviously the overwhelming strength of the team, but the bench is proving it belongs among the elite.
