The Phoenix Suns went through several point guards this past season. (Do you want to remember how bad the situation was? You do? Really? Then check out this post!)
The only point guards already under contract for this coming season are Brandon Knight, Tyler Ulis and Shaquille Harrison.
Knight will be, hopefully, 100 percent after an ACL injury that kept him out the whole season. However, he could be dealt and playing in a different uniform, so at least at the moment cannot be counted on with any guarantee.
