I also think Lowry picking up cheap fouls after foul and playing only 20+ minutes hurt Toronto.
And like BB said, there are no cheap fouls. There's a foul on almost every play in the NBA. The refs either call them or they don't. Smaller defenders will always get called because they have to have "active hands" to be effective. You have to reach. You have to swipe. Steph often finds himself in foul trouble for this very reason. I'm not gonna feel bad for a guy who one of his best skill sets is drawing charges. Drawing a charge is a good heads up defensive play but when you start making a career out of it, it becomes a little cheesy.
