Loma-Rigo is still my numero uno though I have little hope for it happening. Other than that I really want to see Kovalev-Stevenson still, it's lost some of it's glitter so to speak with Stevenson not look amazing recently still, it has to happen. Walters-Loma is another good one I'd love to see.
Klitschko-winner of Povetkin Vs Wilder(Povetkin) Ward-Kovalev(may be pushed back, cuz Ward ain't fighting three times nxt yr) Triple G-Froch(won't happen because Froch is a coward)
The first two are the two that come to my mind as the best fights in boxing. Though neither have the explosiveness of Inoue and Kovalev, add Lomachenko-Rigondeaux and you've got what I think are definitely the three greatest stylistic boxing matches out there. Loma-Rigo even more than the other two would be a 'p4p best' fight. I'll put up with the rest of the year being trash mismatches just to get those three fights.
Kovalev vs Ward Povetkin vs Wilder Usyk vs Lebedev GGG vs Lee Bradley vs Brook Crawford vs Postol Rigondeaux vs Lomachenko Gonzalez vs Inoue Edit: Couldn't pick just three, sorry
