I have like two players that I should be worried about when it comes to injuriess: Rudy Gay and Lin. Gay was fine all last season so that's hardly a concern and I'm sure Lin will be fine.
I keep durability in mind when drafting/trading for players.
my team is also not dependent on any one player. I have no superstar, just a bunch of STARS that will play at a high level. If I lose one guy it won't be a huge concern, no matter who it is.
