I honestly think we are pretty close on this and are pretty much splitting hairs on this subject.
I think at his peak, Bird is one of the goats, comparable to MJ, Lebron, and Shaq. His career was unfortunately cut off short due to injuries, and the thing that is so great about him is that you just can't find another one like him. in 30 years there hasn't been anyone even remotely close to Bird. There are numerous poor man's Jordans, there are a few new Magics (Lebron is a like a cross between a Magic and Pippen, only improved version), but there hasn't been anything like a Bird, where the vision and feel of the game is so unique.
Career wise, I think Bird's peak was one of the greatest, and the thing that really hurts him is longevity. Duncan has surpassed Bird because of it, but Kobe isn't there. Bird is a clear top 10, Kobe is a 10 to 15 player if we are being honest.
Lebron has surpassed them all. I am just shocked at his impact this playoff run, and was ready to put him above Jordan, but then I thought about how dominant Jordan was, and even how dominant Shaq and Duncan were in some of those playoff runs, and I may really be just too into the moment on this subject. I have to think hard about it.
