What Jon Halapio does well, he does extremely well. His initial punch and ability to drive power from his base through his shoulders and hands is truly a treat to behold. Anyone who can physically lift 350-pound Dan McCullers off the earth has immense strength. He is a mauling run blocker at the line, able to seal open holes and collapse defenders. Unfortunately, he’s limited otherwise. His lack of agility and quickness rule him out for teams that use zone blocking schemes that require a lot of movement and second-level attacking from the guards. When his mark lines up beyond his initial reach–especially to the outside–Halapio struggles in pass protection.
