Yeah, I'm on the side that loves our bench ... as a great bench.
But there is no way that an NBA team with this as a starting lineup :
would likely win even 30 games. An NBA team with that as a it's starters would be okay defensively, possibly even above average. But it would probably be the worst offensive starting 5 in the league.
Fortunately, as others have noted: That is not our starting lineup and that is not even a lineup that is likely to see more than a handful of minutes together at most all season. Barring injury, Brad will probably keep at least 1 or 2 starters on the floor constantly, except in blowouts.
