an underrated duo but a duo in the true sense: Isaiah and Dumars.
for pure watchability: Rick Mahorn and Jeff Ruland. These Bullets caused more physical damage than real Bullets. The bad boys before Detroit knew what that really meant.
from a C's perspective, I have to go with Toine and PP as the most prominent duo in the C's history. Not the greatest individuals or the members of the greatest teams but these two were really the C's 1-2 punch back in the day.
