Angles matter just as much as exit velocity. Lara hits the ball slightly harder but the vast majority of his hard contact is on the ground. Lara has 51 hard hit balls on the year. Of those 51, 28 (55%) have negative launch angle. Hitting the ball harder is good but if that contact is just being smashed into the ground it doesn’t really mean much.
Sweet spot rate is rate of batted ball between 8 and 32 LA. This is the ideal launch angle to hit a baseball for maximum damage. Lara on sweet spot batted balls has a 95 Avg EV and 61% hard hit rate compared to Ewing’s 91 Avg EV and 43% hard hit. In that regard Lara looks much better but the difference is Lara only has only hit 23% of his batted balls on that angle compared to Ewing’s 56%.
That’s why Ewing’s contact quality and underlying numbers are far above Lara’s. It’s an angles issue not an EV issue.
Lara has a .285 xwOBACON compared to Ewing’s .427.
