Damn that got me curious so I went digging to find the most successful Warriors halves pairings. (Criteria = minimum 10 games played together)
Green/Johnson = 63% (played 16, won 10)
Maloney/Seymour = 60% (played 20, won 12)
Alexander/Jones = 57% (played 14, won 8)
Witt/Rovelli = 57% (played 30, won 17)
Simon/Jones = 56% (played 25, won 14)
Townsend/Johnson = 53% (played 34, won 18)
Hohaia/Jones = 51% (played 43, won 22)
Green/Nikorima = 50% (played 12, won 6)
Tony/Jones = 48% (played 21, won 10)
Ropati/Rovelli = 47% (played 19, won 9)
Maloney/Johnson = 45% (played 38, won 17)
Ngamu/Jones = 43% (played 51, won 22)
Fien/Jones = 40% (played 15, won 6)
Leuluai/Johnson = 40% (played 45, won 18)
Foran/Johnson = 38% (played 13, won 5)
Moon/Jones = 30% (played 10, won 3)
Beverley/Jones = 25% (played 12, won 3)
Endacott/Jones = 25% (played 12, won 3)
I guess the main highlight there is how few long-term halves pairings we've had over the years.
