Newbie here...saw one called today on TV in a game between St.Peter's & Canisius. 4:51 in 1st half...St.Pete player driving to hoop, contact, a couple players on the floor, announcer& color guy debating whether it's a block or charge while they mention that the refs are huddling. Next thing they say is that it's a double personal foul on Canisius and St.Pete's ball on an endline throw-in.
Question to the vets...are double personal something that you would see often or are they rare?
