The mental make up between the two is pretty far apart to me. Thurman has shown he has no problem coasting and trying to box for preservation, but he has this massive rigidity about him, It almost looks over rehearsed and bit uncertain. The guy is so tightly wound. And I'm fully convinced he has a glass gut, if that's a thing. Spence is just a methodical destroyer and has a genuine self confidence about him. Now I've said it before and again last night.....he really has yet to show a great ability or willingness to move side to side and can be somewhat straight forward and straight back but it's very deceiving. He shifts gears very quickly and changes that when he gets a guy hurt. Brook was literally lifting his leg at one point in the 7th or 8th off the body shots and once the 9th came Spence came out very fluid and looking to end it. Spence positions you with punches and knows how to invest very early, I don't see Thurman taking what he dishes out and think Spence stops him as well.
