Potvin with the 1960's-style headfirst leap.
One obscure incident was during a game against the Islanders, after we traded Kenny Jonsson to get Wendel back. Sundin chased Jonsson all over the ice, crosschecking him, goading him to drop the gloves, eventually penalties were taken. Joe and Harry were having a good laugh over the replay of all the crosschecks and sparring. I don't think I ever saw Mats go after someone without any apparent reason, in that way. Wonder if something happened off the ice between them to cause all that.
