To most this probably means the same as who is your favourite fighter right now. Who is the one whose fights you expect the most, the one that thrills you, who you enjoy watching etc. Wlad gets my vote
It depends on whom they are fighting. Mayweather and Pacquiao are my favorites, so generally I look forward the most to their fights. But I wasn't all extremely anxious to see them fight the likes of Solis, Barrera, Baldomir, Mitchell, Larios, etc...
i'm looking forward to kessler-calzaghe the most. then cotto-mosley, then floyd-hatton. i dont look forward to certain fighters but more so on what fights are made.
If it were 2 1/2 months ago (as in, before his retirement), Erik Morales would be my first choice. And even as faded as he is, I'd still tune in to his next fight if he were to unretire within the next year or so. Erratic is on point with his assessment of Pac, otherwise he'd be high on such a list. Rafael Marquez and Israel Vazquez are two whose fights I've always went out of my way to watch, so it makes it that much more enjoyable to watch them fight each other (three times no less, come next year). Kelly Pavlik is another choice. Even his fights against C-level opponents are fun and never short of drama (if even only for moments per round). As far as tracking their progress, Chad Dawson and Giovanni Segura make the cut as well, though Dawson's last two opponents left a lot to be desired.
