Ray Allen was Seattle's primary ball handler and handled the ball a lot in Milwaukee. Ray wasn't a catch and shoot guy his whole career
He created his 3's by himself and off the dribble for over a decade, maybe not to the extent of Steph but Ray could get his with no help
We all know he was more a traditional SG in his younger days, but he still never spent as much time with the ball in his hands as Steph. Also, how can you concede this and still try to make this argument?
Ray had years shooting as low as 35%-36% and is at 40% of his career, and the last 7 years of his career he was almost exclusively an off-screen spot-up shooter with boosted his career percentage up to what it is. Only 4 of Ray's 20 years in the L did he shoot a higher percentage than Steph's worst.
This isn't a debate. It's not close between them. No amount of nostalgia can make this an argument. Steph has the ball more, shoots more, and shoots at a higher clip. Ray literally has no argument for any advantage over him as a shooter.
