Ryan/Jazz create new white/yellow/black jerseys and start getting set for rebrand... word gets out and leaks start happening which triggers the backlash from fans... Ryan/Jazz realize they've miscalculated and need to scramble to add something back.. Ryan starts promising purple is here to stay.. but its too late to throw in an additional purple jersey to the mix.. so Ryan/Jazz decide to simply rollout the mtn throwbacks again this year (probably easy to produce from nike) and then design a new purple concept that can be done the following year..
This is my best educated guess.. but i think i'm spot on.
