The "out with the old, in with the new" argument seems to be consistent with people's constant complaining that Doc doesn't play rookies and so forth. (Calling Ray 37 when he's 36, etc.)
Bradley's done great in place of Ray, but that doesn't mean that Ray's suddenly not better. Doc will probably give Ray fewer minutes to get him back in the flow, but that doesn't mean he'll come off the bench, or should.
Teams are willing to double Ray because of his shooting ability. Are they gonna do that to Bradley? Like I said in the previous topic, people get caught up in saying that they're tired of seeing Rondo wait for Ray to get open, when the thing is, defenses practically go outta their way to make sure he isn't, and everything else opens up based off that. A lotta people wanna pretend it's not a big deal to hype up the new kid on the block. That's not due diligence for Ray.
