Which currently undefeated prospect(s) will lose their "0" in 2016?

The Charlo brothers are usually ranked in the top 5 guys of their division in most legit rankings. I'd hardly call them prospects at this point. Hell I'd say the same about Joshua, Spence & Julian Williams cuz there are top ten ranked by most legit rankings themselves. Once you are in the top ten I think you lose your prospect title. At least thats how I tend to see it. I think Zurdo is the guy most likely to take an L next year. Seems like he maybe getting lined up with Abraham for next year which is gonna be a fight to see how good Zurdo is & how far Abraham as fallen in his age. Somewhere in the middle of that battle I see a solid chance Zurdo is given his first L. You're right, I was debating whether to put them on there or not but if you look at their resumes it looks like a typical prospect resume. Full of stumblebums.

Smith or Gilberto Ramirez are most likely to step up and take on a "50/50" opponent or close to it so I would vote either of them.

Tough to say,, but if I had to pick one I would say callum. He could taste defeat in a big domestic fight or European title level. I see him being the first one to really step up and that's why I think he has the most chance of losing his '0' Possibly Joshua if he lands a major fight vs fury, Wlad, wilder, Povetkin, etc The rest I assume will be carefully matched and won't be in a major fight till 2017

It all depends on who they fight, all these guys could stay undefeated if they kept getting fed cans
