I used to give Stevenson a small chance against kovalev. After the Jack fight, i'm thinking Kovalev absolutely mauls him. Its possible that Kov gets caught with a counter but I dont see even see Stevenson being able to keep pace with Kovalev, considering the way he tried to feint and cruise through the early rounds against jack. I think stevenson will just wear himself off trying to stave off kovalev with big swings while kovalev stalks him and picks at him. Somewhere about 3 Stevenson gets a notch slower and Kov will sting him with straight punches. I think from there its a shorter version of pascal.
