I love Errol Spence, but he gets hit cleanly and I am confident Canelo would counter him and land a shot Errol could not recover from. It would be fairly easy for Canelo, too. If Errol moves into the weight and gets accustomed to it properly, then I think Spence could win, but it still wouldn't be anywhere close to easy. Canelo landed great shots on GGG who rarely gets hit clean and kept his offense at a stand still, the difference is Errol does get hit clean much more often than GGG, so just imagine what Canelo would do to Spence's offense/style, on top of hurting him.
