Help finding stats?

[portlandoden]

I've been trying to find out how to find a site where I can check when, for example, 3 or more players from the same team have averaged over 20 points per game in the same season. Or, the example i'm after, when 3 players from the same team averaged 5 or more assists per game in the same season.
It seems pretty simple so I'm sure it's out there, but I've had no luck so far! I figured someone here would know where to look! Thanks

I couldn't actually find a tool, but here are the teams from 1980 season and afterwards (might've missed some, sorry):

If the Blazers can repeat the feat this year with Lillard, Batum and Mo that'd be cool. I'm guessing that was the reason you started your search, right?
