He's said himself on numerous occasions recently that he walks around at 138 btw (the same weight he walked around at in his 126 days). He stays in shape. Maybe he walks around for a short period of time at like 142 when he's eaten a few pies but we're not talking about fat weight here. There's a recent video of him last week/this week dipping into an ice cold lake and he looks at his fight night shape.
We're essentially getting the FW Lomachenko who appeared vs Russell Jr (minus the weight cut, which is something I guess), against all of these big cats.
Yeah, he will have to put on 2lbs of muscle to feel more comfortable.
Yeah good point, I think he becomes a little more economical at 135 as a result because he'll be trying to get their attention more. On the flipside, this doesn't bode as well from a competitive standpoint against those who like to rack up points using volume, and even effective aggression. It does make sense given Lomachenko's output dropped from his 126 days vs 132 days in the ams (in a way which isn't solely based on the point-scoring change).
All in all, I'm expecting him to come in on fight night at around 141lbs when he's a fully fledged LW. Puffed up pigeon fighting weight cutters. Unfair in many ways but that's life.
