Depends on how well Danny can hold up against Red's coils and death spores while fighting to get in close enough to use the IF effectively. IIRC, Sabretooth has done well against Red before so its possible Danny could but I'm not exactly sure he could win the majority of the time. Overall, I lean towards Red for now.
Sabes has been outright manhandled by Red. And the fight you're talking about, Red wasn't using his death factor or life drain.
Shouldn't Red still have been able to defeat Sabretooth with just his physical powers and coils though? I would think that would be enough but then again that fight seemed more like a low showing for Red.
