BJ Saunders would lose to the elite MWs. No way will he be able to get away with what he did to Lemieux. Here is this, BJ Saunders does not have great timing, accuracy, and doesn't sit on his punches. He isn't particularly explosive, and is rather predictable against an elite fighter. Obviously BJ Saunders would use his best asset which is his legs, but he will get chopped down by punchers with a good jab and good timing.
Fight would be cancelled after BJSs son punches Canelo in the knackers who then goes crying to his scary mum.
Saunders by schooling. Wins a wide UD and may actually get fair scorecards, now that Canelo has squandered his good will, the judges may not be so kind.
The only one dreaming is you Isal. Canelo didn't beat GGG, who was playing right into his hands, Canelo has never beaten a "runner" convincingly yet, especially not one with the skillset of BJS. Canelo will not be in an easy match for the foreseeable future unless he fights the bottom of the barrel at MW, which will delegitimize him even more. Keep lying to yourself, you're only making yourself look bad in the process, one of these days you'll cut ties with this ginger anchor you have hanging around your neck.
If Floyd's slickness is too much for you to handle then you sure as hell ain't going to be able to handle BJS 2.0s.
