I will add my two cents, for what it is worth. I had the opportunity to see both play, throughout their careers, and Bird was better offensively. I won't quote stats, because my eyes can tell the difference. PP is a very good offensive player, but Larry was in another class. Larry did things on a nightly basis, that broke your back. You could argue PP is a better scorer, but overall offensively Larry was superior.
Did Bird play with better players? Yes he did, but he made them better because of his passing. His offensive rebounding was excellent for a guy who couldn't jump. He knew how to block out, and had an instinct for the game. He knew where a shot was going, and just went to where it should come off the boards. That is something you cannot find in a stat. Is the game different? Yes, but in their primes I would rather have Larry on my team!!
