I remember Bill Parcell's used to refer to some players as JAG's, as in, Just Another Guy. The context was that you don't worry about those guys because they are easily replaceable. You lose one, you pick up another.
Albeit, basketball is somewhat different that football, but the basic principle is the same. The biggest problem with this team is that we have a bunch of JAG's. Get past Rondo, KG, and PP, then everyone else is just a guy. Not terrible players but not really difference makers either.
Now maybe Avery changes things when he comes back. I sure hope so. But in the meantime, I don't really see how picking guys like Martin, Birdman, etc. really makes much of a dent. These guys are comparable to guys already on the roster. Not all can play and decisions might be difficult for Doc. Chemistry could come into play as well.
So really, the only deals worth making are those that bring someone who is considerably better or adds something we don't have. Of course, to get that guy, we'll likely have to give up a difference maker like Avery. But if we could get back size and rebounding (things we really lack), it would not be crazy to consider it.
Some people might scoff at the idea but hey, you gotta give up something to get something. Of course, we can just stay the course and see what happens when Avery comes back. If he can pick up the slack, then sorry Courtney (or even Terry), but somebody's got to sit down.
Bottom line: picking up another JAG is just an exercise in spinning our wheels.
