Do you have anything to back this up? Serious question. I would not be surprised to learn that Klay performs better as a creator, but to me it's unfair to reduce Redick to a guy who "pretty much just catches and shoots" when he's often Philly's first option late in games. I would say the same about Boston era Ray Allen or Chicago era Ben Gordon. There is a crucial distinction to be made between guys who catch and shoot and guys who shoot so well they don't need their feet set, their shoulders squared to the basket, or more than an inch and a split second to pull the trigger. That basically is the definition of creating offense.
My position is that Redick has given you 90% of the production offensively that Klay has over the last five seasons. That's not an opinion it's a fact. I can't begin to imagine what other context you are looking for when I've posted both how many shots they make and how many they take. It isn't as if I'm ranking pitchers by their win totals.
In fairness to your reaction to what I have said, it can be difficult to determine how well numbers and skill sets - even when adjusted for efficiency and the like - translate across different situations. I don't think anybody believes J.J. is capable of putting in 41 on the road in game six of the WCF against a super-human defense. Klay is taller, more athletic, and outright more talented. He is going to hit peaks that J.J. cannot, without even considering the other end of the floor. This isn't the time for the Klay backers to come out because he has few fans bigger than me.
But as somebody who has watched as many Warrior games as me, I would be surprised to learn that Klay creates for himself. The primary creators for that time are Steph, Draymond, and now KD. Hell, Iguodola and even Livingston need the ball in their hands more. That's the whole Klay mystique. Wasn't there a big deal made just this past season about how he scored like 40 points in a game while only dribbling 17 times? If you were drafting a poor man's Klay Thompson you would name him J.J. Redick. And if the two had swapped sides this season or any other season I am not convinced that the offensive efficiency of their respective teams would change much.
