2. Markelle Fultz
Full disclosure... we've beat this drum before. But Markelle Fultz makes so much sense on this version of the Suns' roster. His time with the Orlando Magic was a productive one, and it is there that Fultz got his confidence back after the "yips" issue which plagued him earlier in his career.
The Magic have gotten younger and frankly better, but Fultz was once the second best player for that organization in a playoff series against the Milwaukee Bucks. His shooting is never going to be great, but his driving, passing while pushing into the paint and defending are all above average.
The Suns did a fantastic job of getting both Jones and Morris this offseason, if anything they now have too many point guards for the amount of minutes available. But that was likely done because the front office never would have thought a younger player like Fultz would become available. Now the prospect of him signing a "prove it" deal and moving on next year makes sense for everybody.
The easy solution here would be to eventually trade or cut Morris, allowing Jones and Fultz to handle the playmaking duties. Fultz might not draw much attention from defenders, but it is his own defensive play at the point guard position which would be the most valuable here. There's still something there, and the Suns could pick this guy up for basically nothing.
