Like everything in BB, it depends on the situation your team is in. It also depends on what position you want.
Since you only have 4 players on your team and are being relegated to Div V. I would order them like this:
5 Ball / 3 Ball A+ / SF / 6'3 / 190 (close call between him and the next. I gave him the nod because good SF's are hard to find)
5 Ball / 4 Ball A / PF / 6'6 / 198
4 Ball / 4 Ball B+ / PG / 6'0 / 183 (still good with good potential)
3 Ball / 5 Ball B / PG /6'0 / 183 (the best potential, but at the level you are at you would not even get close to training him
to that level, so the only good it is for is for retail value)
5 Ball / 2 Ball A / SG / 6'4 / 190 (people don't like to see 6th man or starter, if you decide to sell this guy)
Really, you have first pick so I would choose either one of the top two players.
