I would say he was the best. Not only was he an awesome fighter but he would make his presence known - very well known, LOL. Unlike Brashear or Laraque or others who frustrate fans by being total non-factors, Probert was a huge factor. I bet Chicago fans would rather the Wings of had Gretzky than Probert...
He fought all comers and put many down hard, like Dave Brown, Darin Kimble, Tie Domi, Dave Semenko, Stu Grimson and so many more. Plus he'd run a goalie, knock a player around, wig out from time to time. Guy was amazing at what he idid.
