Lot of fights to pick from, what is it? I took out the HW's from consideration because that would just spew a bunch of Douglas-Tyson posts.
How big was Leonard/Hagler? Some other fights that were big upsets... Michalczewski/Gonzalez Barkely/Hearns Tarver/Jones Montell Griffin/Jones? Darchinyan/Mijares Pac's had a few recently.
Turpin-Robinson has to be the right answer. But Honeyghan-Curry deserves a shout out. Maybe Fritzie Zivic over Homicide Hank.
One of the greatest,non heavy weight upset I saw was in 1944, at MSG, when Al Bummy Davis,who was a 10 to 1 underdog flattened the great lighweight Bob Montgomery, in the first round with a series of left hooks. Montgomery was on the same level as Beau Jack and Ike Williams. The crowd went crazy....Al Davis though not a great fighter had the best left hook I have ever seen. Burt Bienstock
Pacquiao vs. Barrera I Hopkins vs. Trinidad (Tito was supposed to win and fight Roy Jones Jr) Lloyd Honeyghan vs. Donald Curry Rosario vs. Bramble Glen Johnson vs. Roy Jones
Would agree Turpin vs. Robinson being the biggest, but then Billy Backus winning the title from Napolés must be up there too.
turpin vs robinson. the only person not surprised was the leamington licker who said he knew he would beat robinson exactly the way he had.
