22 year old Drummond may be a major problem for the Pistons. A historically bad FT shooter and like Cousins has troubles to close out to the 3 pt line and to guard the pick&roll. As Tyrone Lue I would put Love at center everytime I'm in the penalty and trade a Lebron+Love pick&roll versus a hack-a-Drummond on the other side, if he gets deep post position on Love. Obviously a cheap tactic, but Drummond has major holes in his game any competent coach should exploit to the fullest.
Stanley Johnson really brought his A+++ game yesterday. Very mature and fearless for a 19 year old. But in the end the switches on the pick&roll, that caused Jackson to guard Lebron just killed the Pistons. Jackson did a good job on D, but the ref's allow Lebron to dish out so much contact it's simply too much to overcome for such a "small" player.
It's got to be really interesting how this plays out during the series. I would expect Stan to come out with some kind of adjustment.
