Dwyane Wade brings up the controversy via his instagram 10 years later!!!!
Now, I don't know for sure that this pic is of the last foul call. If it is, it does look like a foul on Harris; but what made the call so egregious was that the ref on the baseline didn't blow his whistle. The guy who called it was back at half court on the opposite side of the court from the action. There's no way he sees Harris' hand on Wade's wrist.
Anyway, through 6 games of the 2016 NBA Finals, Lebron led the series with like 31 FT attempts. Wade had 97 FT attempts in the 6-game 2006 Finals. 97! That is insane.
