Although a lot depends on where the two guys are respectively in their training. Like when Floyd was 'beat up' by Spadafora, Floyd was out of shape and gassed, no wonder you lose a sparring session when you aren't hitting your peak and the other guys is.
That said, I have no idea where these two guys were respectively at the time of the sparring.
The Ghost is ever improving though and I can see him beating most of the top guys from 140-135. I think he would be the only guy at 135 who could give Marquez a real run.
