Chris Ballard illustrates that, statistically speaking, Brandon Roy is "remarkably well-balanced"

From his book The Art of a Beautiful Game:

Tonight's [scouting report] provides an in-depth breakdown of Roy, who is an especially tough matchup for Battier.  Unlike many NBA players, who have obvious preferences and known weaknesses, Roy is remarkably well-balanced as a player.  He is equally effective going left (scoring .91 points per possession) and going right (.92), though he shows a slight preference for driving left (54% of the time to 46% of the time).
