Bag drill: get the full shaft onto the bag at impact
A strike drill that uses a golf bag as the target. He wants you to feel the full shaft - not just the clubhead - contact the bag at impact. If your shaft is straight and vertical instead, only the head reaches the bag first, which he calls a flicky, weak position that causes poor strikes. Getting the whole shaft onto the bag trains the stronger impact he's after.
