Watch as Coach Bobby Benson (previously at Johns Hopkins Univ.) explains the first read on pick is to accept or reject it. The second read is to stick or slip the pick. The player must listen, look, and feel the defender to get an idea on how they are playing it. If it is a switch, then you should slip and if the defender stays you should stick the pick. A good way to remember is this saying: "They switch we slip; they stay we stick".
