The fighter that gave Ricardo the most trouble was Rosendo Alvarez, particularly in the first fight.. I haven't watched it in a long time but it ended in a draw and I believe a lot of people felt this was generous towards Ricardo. For some reason I thought this was because Ricardo moved up in weight, but looking at boxrec this doesn't seem to be the case.. Maybe Alvarez moved down? I always thought there was something to do with weight but I could also just be completely wrong.
