Iguodala was sublime in the final three games, making timely shots, getting out on the break, getting rebounds, getting assists and undoubtedly gave Golden State an emotional lift after it fell behind 2-1. Since you like numbers, I already told you he was second in net rating, behind only James.
Defensively. When Lebron was in the floor at the same time as Iggy, his field goal percentage was .351% Lebron also shot just 30 percent on shots contested by Iguodala. When contested by anyone else, James shot 42 percent.
I'm not denying Curry is the vital cog of the Warriors, but Iguodala's impact far exceeds the cherry picked numbers you put up.
