He most likely is walking around more than 180 lbs before cutting weight and actually looks like muscular elite pig pharm product. I can't see who larger than he he had fought in his backyard. Smaller then he yeah, it is easily to see. He is cash cow in murica.
Maybe Plant is happy and scared: dream paycheck will come in, from another point: after he will lost fight vs Canelo, not likely someone will pay him even 500k for his next fight. Why to bother, there is not deficit of up coming guys with holy 0 in fight record.
