That being said it's a pretty pointless matchup to be honest, I don't want to see a horrible version of Spence @ 140 against anybody.
You talk about fighters putting on 10llbs or dropping them in the lower weight divisions like one might talk about a HW bulking up. We can't talk about llbs off or on when considering moving divisions, we need to consider % of overall weight dropped or gained, and when looking at it this way, your match-up makes little or no sense.... Loma, by default...
Lomo depends on footwork but his footwork is nullified by Spence's superior positioning and cutting the ring off. That body attack would be brutal and intended to slow Lomo down for the middle rounds. Lomo won't like how Spence is treating him like a rack of ribs. Shades of a superior Salido! Running away, ain't gonna help you. Spence is a beast in aggression and the constant pressure wears a man down. Spence KO 7
