Parsons was standing behind Lillard even before the play started.....he basically gave Lillard a free path towards the ball. When the ref blew the whistle Lillard immediate took off & caught Parson off guard. Harden was flat footed & was face guarding Wes so there was no way he would have been able to switch onto Lillard who was on a full sprint. It is obvious McHale was trying to prevent LMA from catching the ball which is why T-Jones was solely blocking Batum's view towards LMA's direction. If that's the case Parsons had no business trailing Lillard when all he has to do is run towards the ball unmolested & Batum will see him in plain sight. He should have been b/w the ball & his man...if Lillard cuts towards the baskets Dwight is waiting plus Batum will have to make a tough pass over T-Jones.
