Steve Sailer reminds me why Larry Bird is considered the greatest passer of all time. Sure I'm biased. If you like Magic better overall you're wrong, but I'm not going to quibble.
Three points stick out.
1. The sheer volume is comment in itself. Lots of NBA players have a few plays like this over the course of their career. Birdie did it all the time.
2. You have to see this with 1980's eyes, when this was new. Bird is not copying anyone here, he's developing the craft. People had started doing this stuff on city playgrounds in the previous decade, but it was unreliable. Tricky passes that bounce off other players' noses aren't useful. No one on the floor had anyone dishing them stuff like this in highschool, or college. Even in the pros, there wasn't much of this in the 1970's. You can watch great passers of the 70's - Walt Frazier, Tiny Archibald, John Havlicek, and you will see some very nice passes - very smart, alert, and even a bit of adventurous passing. You won't see much of this. The over the head or behind the neck stuff especially - blind passing was just unknown.
3. The first one is a beauty. But just when you're getting jaded with so many in-traffic back-tip passes, something will jump out at you, like 4:55 and 6:35.
Here's more Bird, if you want it.
