If you want your starters to play more, you can try running slowdown tempo. And you can change your fatigue settings for your starters, but their ratings are impacted as they move through each fatigue setting, so it depends on how much better they are than their backups. You can also set your foul trouble aggressiveness in the player game plan if you don't want your starters sitting if they pick up a couple early fouls. Last thing is to make sure you go at least 3 deep on your depth chart for each position so the engine isn't just throwing players into positions they shouldn't be playing because of fatigue/foul trouble/etc.
Those are some of your options to keep your starters in to try and offset his bench advantage. In a perfect world this all works great, but yea... WIS != Perfect World, so good luck.
