No doubt Andrade did pick up a shoulder injury in the Joanna fight, hitting thin air with haymakers tends to do that. Jessica's boxing has improved since then though, as her second fight with Rose proved.
To have a chance against Shevchenko you have to be superior in one discipline at least; so what would that be in "Muay Thai" fighter Andrade's case, slams? ATT already showed how to nullify them, if only Jessica's opponents would notice.
She would be a decent challenger though and no doubt a lot of folk would get excited at the prospect, just as they did before the Joanna fight, when half Sherdog were convinced it would be an easy ko for the Brazilian.
