I will give you a tp for mcgrady. I was actually just writing up a response that mentioned him when I timed out. He is a really interesting case because his signing still confuses me to this day. He signed with the Spurs in April right before the playoffs and played something like a grand total of 5 minutes in the playoffs. I think the spurs were the only team that offered him a spot, but then they didn't play him.
If memory serves correct he didn't even play when the spurs had a few minor injuries. At that point Mcgrady had become an NBA vagabond after his health betrayed him in Houston. He had forgettable stops in Detroit, New York, Atlanta, China and then ultimately San Antonio. It could just be personal bias, but I had a lot more sympathy for mcgrady trying to extend his career because after the 2007-2008 season he only had one season where he didn't miss at least 30 games and in general the way injuries impacted his career was just kind of sad.
Overall, my point remains that is very unusual for a hall of fame player to sit out more then half a season and then pick the team with the best record (and not particularly cool). Roger Clemens did something similar in baseball but he was at least going to teams that he had ties to. I guess when you start getting yourself in the same boat as Clemens it is not a good sign.
