I guess I don't see Roy as being unwilling to change. If he were a selfish player, he could become a problem. But even last year, when he "dominated the ball", he averaged as many assists as he is this season. It's his points that have suffered, and his shot attempts, and his trips to the FT line for easy points. There seems to be an all-or-nothing approach around here; either Roy adapt to other players, or other players adapt to him. Frankly, Andre Miller, on surface, seems to be the one unable to change his game IMO. Players need to meet in the middle, and Miller seems unable (or unwilling?) to do so thus far as a Blazer.
I don't think Roy is a selfish player. As to whether he's stubborn about his role, or Andre Miller is, I wouldn't venture to guess. I'm not big on making pop psychological analysis (I'm not implying that you are, just explaining why I wouldn't finger either player) considering I don't see what goes on in practices or behind closed doors.
I do wish a Miller/Roy backcourt had been given a real chance before being discarded as failed. The three-guard lineup was never going to be a permanent feature, so it really wasn't a good trial of Roy and Miller together. If Roy and Miller had been the solid starters for the first several weeks or a month and it was looking rocky, that would give me more confidence that the "Roy and Miller can't co-exist" theory was correct and it was time to try something else. As it stands, though, I still think the "something else" is a Miller/Roy backcourt (with two forwards and a center).
Discarding it without a proper trial is, in my opinion, short-changing both Roy and Miller. It is implicitly saying, "They didn't work well together right off the bat and we have no confidence either can adjust to make it work."
In any case, it's no tragedy. Even if the result ends up being the Blake/Roy backcourt of last year, Miller makes a far, far, far better backup point guard than Sergio Rodriguez. But I think Miller is somewhat wasted in that role, and I'll probably continue to feel that way until it's shown, by a proper trial, that the Blazers' offense is worse with something like a Miller/Roy/Webster/Aldridge/Oden lineup. I think that
if Roy could learn to get points on run-outs, catch-and-shoot opportunities and Princeton cuts, Miller would be a net asset. If Roy can't play any other way (successfully) than how he did last year, then fine...bench Miller. But that hasn't been proven, in my opinion.
