If making an argument that DJ and Ainge were both sort of combo guards and both played point and off guard...
Larry & DJ
Jordan & Pippen
I think Wade and James are pretty good but who is their competition? I think Miami has had very good luck with playing against either very inexperienced teams (OKC, Indy) or heavily aging teams (Boston & San Antone) to win their two titles.
I'd also argue, as someone else mentioned, that Pierce and Ray Allen were pretty unbelievable together for the first 1-3 years - with a little better injury luck those guys would have put up 3 titles as a duo.
Lastly, if Paul and Ray were in their primes I say they smoke James and Wade pretty regularly. They were already doing it on the downside of their careers against a James and Wade in their primes.
