I am not sure...Guzman has a good chin and is very fast. Soto should not KD him without finishing the job...i.e. if he KDs him, I expect Soto to beat him.
Even if it's a draw, I doubt they'll call it a draw. If it's a draw, they will either give it to Soto because he's younger or to Guzman, because he's more marketable - politics...
