In this game (2475356), I set the substitutions to "Strictly follow depth chart". I have set these three players as SF: (2540054), (846995) and (709956). Still this guy (3127392) played 5 Minutes in the SF position (he was the number 3 guy in the PG position).
the second SG was injured, so it seems. No one fouled out. But Number 3 was sitting on the bench (started as PG, with high stamina), during Play-Time of the non depth-chart guy. Sp from my point of view, the third nominal SF should have played.Stamina should not be an issue with this substitution pattern (at least not insofar as substituting some player not in the depth chart).
