When they signed Bol they were filling out the last roster spot, now that they are over the limit the cost to cut Bol is no more expensive than any of the other candidates.Waiving Bol Bol and replacing him with another vet minimum player is an expensive way of doing business, but Mat Ishbia has shown no reluctance to spend.
The Suns signed him to a 1yr minimum deal, they were never invested in him.
