I agree. Jazz have 4 solid big men. Jazz would have to get back another big man if trading Millsap or Jefferson. Jefferson is a 20/10 big man and low post scorer. Jazz give up best big man scoring threat if they trade Jefferson. Not too many around anymore. Jazz would have to get a great player back for Jefferson. Corbin needs to figure out how to use Jefferson better. If Jefferson can make any kind of improvement defensively off season he's well worth keeping. Jazz also added much needed 3 point shooting with the Williams and sounds like K Murphy will make team.
