Difference between Groves/Dirrell/Froch is this... Dirrell was far too athletically gifted. Froch was actually heavy handed and punched long. Groves is neither.
Unless Groves can avoid getting hit for 12 rounds he'll get knocked out. He can attempt to be as slick as he wants but he'll still get hit, his best strategy is to plant his feet and throw bombs.... which plays into AA's hands.
Groves has a lot going for him and I do think he can go far, but to have him above AA at SMW at this stage just shows how daft boxing is getting.
Not sure how AA has this reputation of being a monster puncher at SMW. Unless you count him hitting undefended people on the floor?
