Huh? Have you seen how many 4v3s the Warriors get? Have you seen how much Curry gets doubled every single time off of a screen? Have you seen how he gets manned up one step beyond half court because coaches don't want him to see any light of day?
I think that KD and WB are the best duo in a vacuum, especially from a talent perspective. But on a team of 5 versus a team of 5, I think Steph and Dray are the best duo.
Also, I know tons of teams that would love to have Steven Adams, Kanter, Ibaka, and even Waiters (despite his inconsistencies)...
