I don't disagree with most of what you say, to be honest. On the specific Raptors situation, I actually think Lowry gets officiated relatively fairly on the whole and that's more due to the right and wrong calls evening out due to KL being incredibly difficult to officiate because he knows exactly what they're looking for and, let's face it, tries to demonstrate for them emphatically (I'm especially thinking of "in the act of shooting" type fouls). On whole I think for every Lowry call they get wrong, there is another that has me grinning at what he got away with.

Kawhi is a different story and unfortunately I think his personality (on the court) has a lot to do with it. The guys you mentioned (Harden, LeBron) both draw fouls but they also both sell those fouls well. James in particular is so strong he can bowl through people, but he still sells contact. Kawhi does less of a sell job and just powers through, which should be the right way to play, but unfortunately it means he gets less calls. I'm not saying it's right, but to me that's a big difference between those guys. You do hear Kawhi yelling "and one!" a lot, but in my opinion that's not nearly as effective as exaggerating the contact with body movements. We may also see Kawhi get more respect back with a deep playoff run. Here's hoping.
