Given that Wills has a winning record against Langford throughout the latter's prime, I'd pick Wills to have KTFOed Dempsey. Dempsey ducked.
Can I add that he had an unimpressive title reign and weak quality of opposition, or is that too obvious? Why are you so triggered?
Ohhh, you're trying to trigger me like how my Dempsey post triggered you. Sorry, Biden's no hero of mine and I couldn't care less about trans women & female locker-rooms.
Langford was 31 years old and had been professional for 12 years when he FIRST fought Harry Wills. Langford fought Wills again in November and won by knockout. It wasn't until over a year after that in December of 1915 when Langford was 32 going on 33 that Wills managed to win a newspaper decision. Langford also knocked WIlls out again 2 fights later in February of 1916. Langford was still good but he wasn't prime at all. Not in his 30s and probably 40-50 lbs over what he probably should have been fighting at.
