I mean, the "sales pitch" is just the rosiest take on a situation that can't really be changed, for now. It's a team of scrappy role players. Put another way, it's the best two bench units in the league, but there's no starting lineup.
Some nights they'll look like a 10-man dynamo that is far more than the sum of its parts, some nights they'll look like they brought a knife to World War III.
The Celts have a tough opening schedule, so they might hang around .500 or even below .500 for the first month or two. It'll get easier later in the season when they face the weaker Eastern teams multiple times and some of their other opponents start packing it in or resting their stars.
Just pray that Nets pick turns into a star.
