I think Spoelstra is great, he coaches well... but a lot of our struggles on D had very little to do with strategy and a lot to do with execution, we were switching on the ball and sending an extra guy at Jimmy a lot, the problem was mostly execution, we far too often made the help late, or let him go baseline instead of herding him inside. Rob in particular made a number of mistakes where he dropped too deep. even then our halfcourt D wasn't that bad, they did a lot of damage in transition and semi-transition when guys were slow getting back or didn't find the shooters, and off poor box-out offensive boards. On offense we were getting what we wanted frequently, we just committed a ton of bad turnovers.
Spo is a better coach than Joe, but this game was lost in execution not gameplanning. We turn it over less, we make our FTs, we box out, guys run to the shooters instead of jogging.. we win this game pretty easily.
