Langford at 175lbs takes on these two with a 3months breather between, modern gloves 15rds how would he do?
Hard to say because the two mentioned are still active and prime. If I had to put money on anything, if you're there to be hit, Langford will hit you. If Langford hits you he likely knocks you out. So I would expect Langford but for all we know Kovalev unifies and rules for a decade and goes down the divisional goat.
