I never said there wasn't a difference Beal is clearly the inferior player especially when Defense is considered. As far as injuries go, yeah that is a knock on him also but Bane played 69 games last year and 42 and 58 the 2 years before to Beal's 53, 53, 50 so it's not as big as you may think it is.
When Beal has a bigger role like he did in Washington his output only gets better, because he is just a much better shot creator than Bane.
Also it's hard for me to believe Bane is going to get much better at this point, maybe ever so slightly, but usually 26/27 is about when a player is as good as they will ever be unless they have an obvious hole that can be fixed - which he does not.
My point is the the difference in perception between the two is laughable considering their actual impact on the floor.
