Vlad had the second hardest hit ball in all of baseball, behind Stanton, ahead of Judge, Pete Alonso, Kyle Schwarber, Nelson Cruz, Mike Trout, etc. You can't fake that, that's 80 power. Did he hit the ball hard all the time? No, of course not, otherwise his performance would have been a lot better. That's already an improvement he's made from last season to this one. Among qualified hitters he also had the second highest avg HR distance.
I get it, I would have loved for Vlad to have hit the ground running like Soto and Tatis, and it's annoying that he hasn't. But he's still incredibly young and talented, he has plenty of time to figure it out. Eloy is also significantly older compared to those guys, to the point where I don't think he's particularly comparable as he's closer to this physical prime than any of these guys. Having two years in your early twenties on someone is a big difference physically. I'd be a lot more scared of his K/BB rates compared to Vlad.
