Interesting direction this has taken, and not one I'd have expected when the thread began. I wouldn't think anyone would argue that KG was a better scorer than Bird just because he passed him on the all-time scoring list so I'm surprised that this has turned into a KG vs Bird thread.
That said.
One of the ironies that I've spoken of continuously since KG has put on the green is that the Celtics added arguably the best player of his generation to the team...only very few Celtic fans realize it because they weren't really following KG before he got to Boston.
I see in this thread people saying that KG was a top 5-8 player of this generation, and using that to illustrate the difference between comparing someone ranked 7th with someone ranked first. The problem is, there's almost no way to logically rank KG that low. The absolute worst you could put KG in the 2000s and support it logically is 4th, and even then it's 4th-a-lot-closer-to-1st than 7th. By a lot of objective measures he very well could be the best player of his time.
So in that respect, I see absolutely no problem comparing KG to Bird. Unlike some in this thread, I did get to watch Larry Bird's career. He was always one of the top 2 or 3 players in the game for his generation, with several years when he was the best. He had one of the largest on-court impacts I've ever seen, and the numbers don't always due that impact justice.
The thing is, everything I wrote in the previous paragraph could just as easily have applied to Garnett as well. In the history of the NBA, no superstar player has ever had to do as much with as little as Garnett over the course of a career. None has faced the level of competition that KG consistently faced in the postseason with as little help as KG had. This isn't even an opinion statement, it's as close as a sport can come to objective fact. You can argue with me if you want, and I'd gladly take on the debate (though it would further derail this topic) because I've spent some time on this over the years, but you'd lose.
Garnett's career is almost like a science project. It's like someone said, "let's build a player that is the basketball descendant/combination of Larry Bird's genes with Bill Russell's, only let's put him in the worst possible position to succeed and see what happens". If I let myself I can get pretty sad that now, when KG FINALLY has a team worthy of making his legend, his body has started giving out on him. It's a real shame.
Nevertheless, there's still no reason that KG can't be compared to Bird, or anyone else in history. He's reached the point where he has accomplished things that only the best-of-the-best have ever done, and (like all of the greatest) he has his own unique accomplishments that no one has ever done. Whether you consider him top-25, top-15, or top-whatever on the unofficial "All-Time List", he's earned the right to be mentioned with the best.
