Kevin Garnett (prime) vs Tim Duncan (prime)?

Tim Duncan is the greatest power forward to ever live and Kevin Garnett is the 5th greatest power forward ever. Even though Garnett didn't have a great supporting cast in Minnesota, he always failed in the clutch. David Robinson wasn't clutch either for San Antonio which is why the Spurs weren't a great team before Duncan arrived. Once Duncan arrived, he carried that team to 4 championships.
