Size is overrated but size does matter. Especially in the lighter divisions. I think Crawford was legit coming in at 150 lbs or more in the ring while Lomachenko was a small lightweight. Lomachenko's amazing angles, skill and speed will keep him competitive BUT once he gets hit by a big shot by Crawford, he will go into defense mode like he did for several rounds vs Lopez. The power difference is too much. Crawford has the power to hurt Loma but not the other way around. A great small fighter can usually only beat a great big fighter if the great small fighter hits hard enough to get the bigger man to back off. Crawford by comfortable decision even though Loma is the greater fighter overall.
