What if empty chart was implemented as 1- bot lineup (highest salary on PG, then SG and so on) + 2 -coach picks from depth chart ?
The 1st would give a disadvantageous 5 starters, the 2nd would make the substitutions play their 10 minutes anyway. This could solve the problem ... better ideas ?
IMO, there even shouldn't be any "let the coach decide" strategy because it has the same impact on the subs, defensive rotations, played minutes etc.
Or if it does, there should be a coach as additionnal staff member (with levels and quite huge salary ... everybody cannot afford Doc Rivers nor the Zen Master)... but this is another issue i presume ^^.
