IMO it seems pretty clear that they know what's coming. The question is whether they're picking up something from the Jays (maybe a fielder is moving early or something), or whether they're actually cheating.
The Raptors strength is having guys who can play great defense and don't constantly have to have the ball in their hands. Harden is pretty much the opposite of that.
It feels like he's just trying to force things. He doesn't have the ball handling skills yet to be driving the bucket with guys like Smart around. They'll strip him every time (especially in the playoffs when the whistle disappears). They need to get him in catch and shoot situations. No more drives. No more 3s for him this series.
Smart has been flopping all series long (and has been fined for it already). I don't know why he gets any calls at all right now.
Really good win. Both teams played incredible.
