naw, the plan is foolproof so long as the people running it aren't fools: Stop the 3 point game forcing them to try to come closer to the rim, where Whiteside would then defend the inside.
Problem is that whiteside has stunk defensively and that plan hasn't worked out because he's a knucklehead.
so then we're left with either defend the 3 or defend the interior because our initial plan to defend both has failed thanks to whiteside being a chump. If Bosh was playing we'd be defending the PnR without much of an issue but alas he's done for the year.
