spence being the bigger puncher sure wants his target to stand there and take the punishmant like all the slow footed c class opponents he has been facing
now for the first time he is going to face somebody athletic, somebody with upper body movemant and somebody with footwork and speed. it would be he would train his boxing style to adjust to brooks style while also maintaining his power and aggressivnes. but like danny found out when he lost to the slicker, with better footwork thurman. if you want to be at the very top, you need to be able to beat brawlers and boxer who move a lot. by saying "dont move, stay in the middle of the ring" soence is basicly admitting that he has a problem with brooks slickness and wants no part of that
i see spence the winner, but if brook can focus on footwork/footspeed and doing a fight à la mayweather/lara than the slower spence might have a evening of problems.
