I think Spence has all the tools and intangibles to win. It would come down to how well he takes Curry's power, who it must be said, punches harder than anyone Spence has faced. Both being from Texas, it would be an ultimate grudge match and both would be super motivated. Gun to my head, give me Spence via come from behind late rounds TKO.
Y'all know me, so this would come as no surprise: Spence is too much man for that fairy. Stops him late.
Call Curry a fairy all you want, but he's never been spotted out rocking cowgirl boots and a satchel.
