The Phoenix Suns roster has been fairly simple to figure out this month. Each team is allowed to have 15 NBA players on the team at one time under NBA contract, and the team happens to have exactly that. They can also have up to five more players around on training camp or two-way contracts, and the Suns have four of those.
The simplest roster decision is to keep the 15 under contract, secure two of the other players on two-way contracts, and release the rest. Easy peasy.
But building the best possible roster is not about making the simplest decisions.
