What's the most unlikely rivalry in the history of boxing?

[ICB]

Ivan Robinson Vs. Arturo Gatti x 2........this one always blows me away.I thought Gatti would finish what Cardona started but more suprising was Ivan standing in and going hell bent in an awesome slug fest.

Ivan Calderon would of been stopped in the 1st fight had it been 12 rounds he was out on his feet but i've seen a few of his fights he looked like a good skilled fighter quite suprised he didn't achieve more.

Gatti was fighting Jr.Flys ?. Robinson really shocked me that night...He was a solid boxer but that night,they needed a phone booth,great fight.......another fighter in a long line that have held on way to long staying around.

Yea i corrected it just noticed my mistake i just watched an Ivan Calderon fight so he was still on my mind but i remember they were comparing that fight to Meldrick Taylor vs Julio Cesar Chavez which is a good comparison Robinson used good combinations and boxed well on the outside but often exchanged much more than he had to and had it been 12 rounds we would of seen another Taylor vs Chavez like comeback/ending but without the controversy.
