Don't Make Me Use The Bat
In fact I think it means pretty much everything BUT blocking shots. Normally its referring to getting your hands on the ball in a way that does not show up in the stats. Knocking the ball away or loose, disrupting, trying to create havoc. Also of course leads to a lot of fouls. We don't really have many people naturally good at that though. Ron, Cisco...maybe Kevin + Douby, maybe Kenny if you squint hard enough.
