When Brandon Roy retired for his first time Lebron said that the NBA just lost the best shooting guard in the league. LBJ doesn't really like to give other players credit besides himself unless he is asked by the media, to go out of his way and say that speaks volumes.
Roy was incredibly fun to watch, he didn't have the jaw dropping dunks everyone loves to see now days but he brought the same wow factor by making people look like fucking morons when he had the ball. He could finish with multiple defenders in the paint and knew how to get to the free throw line.
If the guy didn't have such fucked up knees he could have gone down as legendary.
