I actually think Klay, Dray and Manu are rounds too early.
I put Klay, Ray Allen, and Reggie Miller all right next to eachother in my rankings and considered them all round 5 players. Three best spot up shooting guards in NBA history with an easy skill to fit into these all-time teams and provide value. Reggie is a little more clutch, Ray has a little more ball handling, Klay has a little more defense.
Manu I like because he's a guy that you know can come off the bench and perform and be a team player. At the beginning of the game, I considered him a 6th round target for that.
Dray I think was a bit early. I don't think his defense would look as amazing against all-time greats as it does today, but he's versatile, can spread the floor, can pass, and is an amazing screen setter. I think he might defend old-school SFs better than he can the old-school PFs as a primary defender, but still have some versatility/ability to hold his own on switches.
