Ward would need to leave Oakland and jump to LHW to make it happen. Ward's had the best opposition as of late in the entire sport, though it was in advantageous situations to himself. He's not exactly a star, not even close, he will need to take great risks to get to that level. People say - Mayweather only fights in Vegas. Yeah... Vegas is an economic monster, Oakland is a dump.
Ward would beat GGG with ease. I would like to see him fight Kovalev. Kovalev is bigger and a lot better than GGG. But I still say Ward beats Kovalev similar to how he beat Abraham.
