Not that I'm weighing in one way or the other about his foot being injured in the fight, but you don't seem to be considering that could've re-hurt his foot doing that dumb shit in the first place and thus it wasn't capable of doing it in the fight. Or re-injured it during the fight.
I mean, what he does before hand is irrelevant to what he looks like on the day in question lol.
In round 1 Khabib simply holds on to Conor and lands 18 strikes while Conor lands 38. I agree Khabib should've won from the positional advantage he held the majority of the round, but active he was not.
As to whether or not you feel Conor can finish Khabib after round 2 is rather irrelevant as the possibility exists on any strike. Why would you risk that? Which is why Khabib didn't and continued trying to get the fight to the mat.
