@Roy.... Scalabrine has championship pedigree & I'm not clamoring to get him back. We need youth & athleticism & size to pair with the old dogs, not just another old dog! I know Jet can ball no doubt but it's a weird fit here being Bradley already isn't a prototypical SG himself. If he is our backup PG im ok with that, but can he guard the Wade's & Kobe's & Harden's? Because we are gonna need that from him.
I suspect that is why they want Ray back as well, because no, Terry isn't going to be asked to cover those guys much, that will be for Bradley, who has shown he can cover Wade, and perhaps Allen. As to the age question, that is another reason to get both Terry and Ray, since they are both advancing in age, they each have to do less and both should be fresher for the playoffs.
I am actually more concerned about Ray than Terry though in terms of limiting his minutes. We all might think its best for a 37 yr old guard to play less, Doc and Danny may think so too, but I think Ray still wants to play 35 minutes a game. Also, like starting pitching, figuring out how everyone can get minutes in an 82 game season, discounts the almost certainty that someone will do down for any # of games. This kind of depth protects against any major dips if/when one of them is out.
