Very difficult, Laguna defo has the speed to stay outside and score. Taylor has the speed to get off combos even on a guy like this. I'd go for Taylor down the stretch, he's probably stronger as well. I rate Laguna higher in terms of at their respective best weights though.
Well Laguna was a pretty classy fighter and fast but i think Meldricks punches in bunches and being the naturally stronger and faster guy takes it toll he would have his trouble though at times but would win a somewhat close but conving decision.
