The Jazz traded fav-favorites like Alec Burks, Joe Johnson and Jae Crowder, and they walked away from Ricky Rubio. Surely, they can move on from Joe Ingles.
Thats not a good comparison, Joe has meant WAY more to this franchise than any of those guys you listed. I mean Crowder and Johnson were only here for like a year and a half and Rubio two years. Joes been here for his entire 8 year career and has been an enormous part of the culture and identity of this team, not to mention everything he's done off the court in the community.
Having said that, he's definitely not the same player he was. Age has obviously caught up with him and I will completely understand if the front office decides to move him.
