My desire for these four Point Guards is pretty simple: Play Barbosa and Booker at the point as sparingly as possible, and work Archie Goodwin and Tyler Ulis into the fold as much as possible.
Barbosa needs to be an end of the bench kind of guy. He should not even have a role as large as Ronnie Price as the younger guys should be given the vast amount of time on the court. However, while there is no way the Suns trade Booker, and Barbosa may pretty much be un-tradeable, there is a market out there for Archie Goodwin, and if I am the Phoenix Suns, I probably listen.
As mentioned before, if I had my druthers, I would look to trade Brandon Knight early on in the season, if there is a reasonable offer in return. But that may only be possible if there is faith in Archie Goodwin, or another backup Point Guard is acquired in the deal.
However, if that proves to be impossible, then moving Archie Goodwin may also be a viable option, and one that I would take serious trade offers into consideration.
Archie is in the last year of his contract with the Suns, and while there is no way that he is going to break the bank with an extension, potential pays, and if his agent believes that his potential is worth a higher salary than the Suns see themselves willing to pay, then a move may be necessary so he is not lost for nothing in return.
A trade of Goodwin for me though is not a necessity. I am personally hopeful that he is a solid piece for the future, and if either Bledsoe or Knight are moved, then Goodwin will certainly see more time on the court, a situation that could either be beneficial or disastrous for the Phoenix Suns, but an experiment that I would be all in to see.
