If giving Bradley a chance means less minutes for Moore, it isnt worth keeping him.
Who/what says it does?
Unless youre saying that he wouldnt be getting any minutes (in which case keeping him is a waste to me), then whos minutes is he getting? He's a guard, so he's either playing the 1 or two.
Rondos gonna play like 35 mins. at PG, Dooling will likely play the remaining 13. Ray is older, and has been playing too many minutes the last few years, so this year I can see them trying to cut his minutes back (plus Doc has said he'd be playing Bradley more at the SG spot). So the minutes to be had are at SG. Once Ray and Marquis are out of the way, who is next in line on the depth chart a SG? I'd say Moore. So if thats where Bradley is given time, then it IS coming at Moores expense.
The only way it wouldn't be at Moores expense in terms of minutes, would be if they ONLY either got time in the backcourt together. But in that case, they'd be playing Moore at PG, with Bradley at off guard, so Moore would be forced to play out of position just to give Bradley time at SG. I dont see any scenario where Bradley gets play time, that isn't coming at Moores expense.
