I think Rolls has no chance vs GG. Odds are non usable, you cant bet on that match.
Agree, odds are not worth the risk, i could even bet if it is 1.05 for GGG but not 1.01.But we saw Ruiz vs Joshua, how it ended 
For sure GGG have seen the fight and for sure he don't want to be like Joshua, besides Rolls is unknown fighter to many fight fans.
