On defense, limit June Mar's touches, take seconds off the shot clock, and make others beat you. On offense, target June Mar in transition and in PnR.
He did make a point that not everybody has the personnel to punish SMB on both ends.
"But as obvious as his weakness sounds, exploiting it over and over again is easier said than done; great players, coaches and teams often find a way to alleviate the blow and overcome the hump, which is how Fajardo, hands down the most dominant PBA player of all time, and former head coach Leo Austria have won nine titles together in the first place.
Additionally, teams don?t always have the manpower and the consistency to press on the hurt on both ends of the floor. Some teams can make Fajardo move his feet on defense then fail to contain him in the post on the other end. It?s the inverse for others ? they?re capable of making Fajardo work thrice as hard for his touches, but they don?t have the juice on offense to threaten him enough on the other end."
You need the plan, but also the personnel to do it. On offense, players who could make pullup shots off the PnR. On defense, the big bodies to guard him in the post.
