I see what your saying about Spence’s gas tank and I agree with you partly. I think both took training camp serious but Porter’s conditioning was unreal. Porter fought the fight of his life. His adrenaline was amplified. Fear drove him to fight like a man possessed, how else do you explain how he walked through all those low blows. Spence wanted a war and got one but I agree, his conditioning maybe compromised due to his weight in between fights. On the flip side though, one more fight like that from Porter and he can kiss his prime goodbye, he looked great but in a rematch Spence stops him late or boxes circles around him just to demonstrate that he has ring IQ.
