That depends on how that kind of outcome comes about. If Brook is super defensive and barely throws anything in an effort merely to survive, then no. If Brook is clearly trying hard to win the fight and is just overmatched, then yes.
Normally I'd agree but when a large and durable Murray tried to survive and failed it makes a WW doing the same and succeeding look very impressive.
Golovkin will be fighting Brook and the judges, referee, boxing commission, etc., he has to knock Brook out to get a draw..............so he should go for the knockout.................hard to do with the referee getting in the way, but looks like he will do it anyway..........
