Rewatching this again and it's still interesting to see how well their styles meshed. Loma vs Haney was a great tactical fight and I think Haney vs Shakur would be another good one as well. I'm still convinced that Shakur will likely get the better of Haney should they meet down the road.
I think Stevenson is the best out of all those guys in that size range. Haney would not be an easy fight, of course, but I think a 7-5/8-4 type decision would be most likely. Not a barnburner but a great fight if you enjoyed Haney/Loma.
