You think Jones beat Brook in the first fight? Brook boxed his ears off for the first 7 rounds then gassed and got his nose broke. Still clearly won though
I think Carson earned no less than a draw in that fight, (knew no way he would win and it was a surprising effort on his part) Either way, Brook avenged his close win so it's a moot point and Vargas isn't the type of guy to put that type of pressure on Brook to take him out his comfort zone.
