Going by the listed wis position is probably most fair.
Had an idea to make sure everyone gets a top four pick in a round with this format, would take a lot of using random.org though and it's hard to explain. 6 rounds (PG SG SF PF C 6th Man). Lump owners into 6 groups of 4. Then then each group cycle through their slot in the draft. For example, group one could get picks 1-4 in the PG round, 5-8 in the SG rounder, ect 20-24 in the 6th man round. Group two may have 20-24 in the PG round then 1-4 in the SG round. Then you randomize the four owners in each group for each round. To make the 6th man round more useful, do it last with a choice of any undrafted player at any salary. Maybe increase the cap by a couple of million.
That's probably too much but I was thinking about it earlier.
