You guys are thinking a 17% shooter is suddenly shooting over 40%, in Finals, with weight of the world on his shoulders? If you have any head, use it when you think.
When he's taking his 3's(it should be noted that he hasn't that much anyway,only 15 or so in the playoffs), he has no defender within 10 feet of him. Who won't be shooting over 50% in those conditions?... Oh Dwyane Wade won't, he'll be shooting 40%.
