True, if one is looking at just a straight forward fight.
Gambit always struck me as an intelligent fellow. And whilst Juggernaut would win in a straight physical contest , I'm sure Gambit would know this and have far more sense than to accomodate the Juggernaut in this regard.
I am sure it would not be difficult for Gambit to outwit him, Juggernaut was always lacking a bit in that department.
Brains over brawn and all that.
