Are We Overestimating Cottos Greatness?

Im a big Cotto fan and I agree 100% with this post and it is one of the best assesmenst on Cotto I have read, here. Yes he hasnt shown as much greatness as the three. This weekend will tell us a lot about his status..
remember Tito and DLH fought much better versions of Mayorga a younger stronger more letahal version than the one Cotto faces Saturday, even Mosely displayed his greatness in the KO. for Cotto to simply win a close one will for me prove Cotto was a cut below the three and just very very good as opposed to great, that great moment is still out there for him....I hope he has the stuff and proves it, however if Mayorga lands the shots Yuri Foreman landed? I see Cotto out cold and Mayorga's greatness as one of the great brawlers confirmed.
