Sergio Martinez vs. Herol Graham

You can actually draw some similar career parallels with them.

Both have pretty sparse win records, both had trouble getting top fights for a long time.Graham was more dominant against a similar level of opposition Martinez has fought, but peaked much earlier than Sergio and didn't embarass himself against any unskilled Mexicans.Both have been thoroughly overestimated by their fanbase at some point too.Martinez right now in fact, though hopefully no one still calls Graham the best British fighter never to win a world title.
