I have the video of Probert's breakaway goal, his skill set was underrated because he made a career out of playing tether ball with peoples faces.. Grimson on the other had made everyone duck when he took a shot (anyone remember his slap shot in game 4 from the '92 finals?).
His cocaine addiction was a culprit in some way, especially if he already had a genetic predisposition to heart disease. The cardiotoxic results of cocaine can stop a heart cold, and the lasting effects can be devastating. Wouldn't be surprised if he had arrhythmia or ventricular hypertrophy.
The legend that is Bob Probert's meat hooks will remembered and talked about for a long, long time.
RIP
