I am not all that experienced with using Zone as a stand - along defense, so far I have used either a combo, man to man, or Press with my other teams, but this year, for the first time, I have switched to a full zone with VMI, with largely the same post and interior players. . and my interior defense has been much better and I have been collecting a ton of blocks(Yes its only two exhibitions and two real games - but. . . is there a reason for this? I always thought man to man was the more effective defense for blocking shots, but the few times I tried plain zone last season and the games in this season, my blocks skyrocketed.
