Well i usually do coaches pick from depth chart so we both decide on who should play. It depends on your starters and subs, if your subs are good maybe let coach decide but if they bad you can also do a let coach decide. Strictly follow depth chart will most likely get your starers 36 min, subs 10min and reserves 2min if no foul trouble. If a sub is on fire let coach decide will play him longer for the period he is on fire for, while coaches pick from depth chart will let him play but may take him off before he starts to go bad and strictly follow depth chart will most likely take him off while he is on fire if he gets his mins.
