Taylor has speed, power and skills. However, his stamina is more than questionable and we have seen that the last 2-3 rounds are absolutely lethal for him as he gets drain to the point where his body can't sustain nothing no more. No good for 12 rounders, head took enough shocks like that. His only chance to spark again would be to fight 8 or 10 rounders but definitely not 12 and even then, he'd be better doing something else of his life and way less damageable for his future.
