I'm assuming this isn't a serious question but in case it is - coaches don't care about the number of fouls. They care - every time a whistle is blown (for any reason), or a whistle is not blown (for any reason), they are fighting/yelling/politicing for those situations to lean more favorably to their team, and critically - at the right time. That's it. Add in the fact that lots of teams (like Iowa State) often foul by design via physical play, the number of fouls called isn't the concern. Plenty of times Iowa State gets favorable rulings and favorable games from officials even when we are called for way more fouls.
Why does Kansas seem have ALL the bounces and luck in Phog down the stretch of games!? Why don't ya ever see a Kansas travel called with like 2 minutes left? Because an official has been listening to Self in his ear for 38 minutes.
