Peak Ray Allen had only around 45% of his shot attempts off a pass..he was very capable of creating his own shot, he was a solid ball-handler with quickness and above average athleticism..
Klay Thomson is horrible at creating his own shot..his ball-handling is very poor and he relies heavily on his teammates to create looks..it's part of the reason he has struggled in most of his playoff appearances..over 80% of his shot attempts have been directly off a pass the past 2 seasons
Warriors will just trade him for a nice package when it's necessary..they won't get equal value, but his playoff production can be replaced by committee..
