3. Reggie Bullock Jr.
Admit it, you hadn't considered Reggie Bullock Jr. until right now. Still only 33-years-old - and having shot over 40 percent from deep in 44 games for the Houston Rockets last season - Bullock Jr. could fill a niche and needed role for this group.
That of the long-range shooter who stretches the offensive end even more for the star trio of Devin Booker, Kevin Durant and Bradley Beal. Bullock Jr. isn't on the same level as Grayson Allen or Royce O'Neale anymore - themselves fantastic 3-point enthusiasts - but his large from means he can still give a little something on the defensive end as well. Plus, you know... offseason at Reggie's island.
So too can Allen and O'Neale - both might even be better than Bullock Jr. - but he would be another option for opponents to worry about on a nightly basis. We're not about to compare him to Klay Thompson and what he can do for the Dallas Mavericks, and yet Bullock Jr. could be an extreme discount version of that.
High level shooting mixed with so-so defensive play, all the while standing in the corner and creating space for others. Maybe the Suns don't need such a specialist with this roster spot - they could go younger with more upside - but Bullock Jr. is at least worth some consideration.
