Malignaggi told NYFights.com: “Eight rounds, good work.
“I can’t disclose too much but McGregor is no dummy.
“There’s a method to his madness. He has an idea of what he wants to do and how he wants to do it, he’s not clueless.
“He’s not your conventional boxer by any means but he’s capable and his power is good.
“Whether that can be effective is up to him, but he’s no dummy.”
