I wonder what kind of inter-sibling rivalry the Zeller brothers have. Speaking as someone with 2 brothers, FullOfBulls and FeelTheHeat, there can be a lot of tense times when competition is involved. For example, FullOfBulls is regularly defacing these descriptions. (FullofBulls was here DownToBuck is a LOSER)
Anyway, Tyler Zeller has shown himself to be the superior brother in the NBA, and his career high 20 points against the Celtics further cements that reputation.
