The guy is extremely talented but he can't put a dent in real 135lbers, it's only going to get worse when he moves up to 140. Great handspeed , boxing skill and ring IQ but he can't punch. Even coming in at 153lbs he couldn't wobble beltran.
That's his style, he's a mover so he really doesn't sit on his shots. He fights off the back foot. He's gonna get hurt at 140, theres some big boys there.
How can you tell from this fight though. No punch really landed clearly, except from the jab. All the other punches Bertand rolled well with the punches or partially blocked it.
Beltran is an extremely one-dimensional and tough fighter. Straight ahead little power. The top boys at 140 I favor over Crawford.
