There's a big difference between "injury prone" like Love where it's a fluke (hand) or malicious (shoulder) injury. I'd say Kyrie has been more injury prone since he's seemed to miss time pretty much every year for some sort of injury. On the bright side with him they are all different so it's hopefully just a mix between being a little fragile and unlucky. You have the true injury prone guys like Rose that had one major injury and continue to have problems with that for the rest of their career. He looked great last night completely rested, but he'll probably look like garbage tonight when they get rolled by the Raptors. Give the Cavs credit that they've done the best they can to be deep enough to deal with injuries if they do pop up. They have Mo as Kyrie insurance and Frye/RJ as Love insurance.
I just hope that Frye is the open 3 shooter that they say he is and not a big let down like every other guy the Cavs have brought in over the years. I think JR is the only guy that didn't start his career with the Cavs that has shot the 3 as billed when they got him. I'm looking forward to the Kyrie, JR, Lebron, Love, Frye and Kyrie, Delly, JR, Lebron, Frye lineups to see how the lane opens up.
The thing I never really understand with basketball, if you have depth why not rotate more often to allow guys to give 100% effort on both ends for shorter periods. Why not spend the first 3 quarters with something like Kyrie, JR, Lebron, Frye, and TT for the first 5 minutes then sub in Delly, Shump, RJ, Love, and Timo for the next 4-5. In the Cavs case they would probably need to have Love with the starters for the first rotation of each half as a stretch 4 and then the focal point of the offense with the second unit. Go balls to the wall on both ends because you know you'll get to rest in a few minutes to catch your breath. When the 4th quarter rolls around go with your best 5 if the game is tight.
