Recent reports say that GMs around the league consider that to be one of the worst contracts out there, so I guess it depends on your definition of toxic. Teams with enough cap space to take Ryno without sending salary back were asking for 2 first rounders.
Jazz can handle that bad contract for 2 season and then its an expiring. The Jazz would have to dump their bad contracts like Burks. Its not like he isnt bringing something to the team. I would not do it alone it would be for getting Gordon as well.
