Regardless of "fit", and you can't tell me Duke has better defensive players than us... this thread is about how they play it.
Nobody, not even Bonzie Colson, the prototype player to put in the middle of the zone, is beating you with two point jumpers. They took away the 3 ball so the only looks Pflueger and Farrell got were from deeeeep, while contesting layups.
No dunks/No three = No momentum. If we played guards/wings on the perimeter and recruit shot blockers to contest near the basket while allowing teams to shoot mid-range jumpers in semi claustrophobic parts of the court... we would be better defensively and the zone would become a serious weapon in modern day basketball. Add to that a token press that leaves team 20 seconds to initiate offense, and we could seriously disrupt anyone we play based on the types of players we recruit and commitment level to zone defense.
