I'd go with Mitchell as well, can't really see any of the others challenging for a title too soon. Macklin and Rhodes shouldn't be too far away from challenging but I don't see Rhodes winning and Macklin is still a few fights away imo.
I think Cleverly. I see Rhdoes, Macklin, Burns and Mitchell all getting shots before then but they will come up short.
Just kidding with Hatton, from the list posted I wouldn't be surprised if none of them won a "proper" world title.
I know IBO's quite crappy, but I still think it's a tad unfair on ole Matthew sometimes, he's cack, but I wish him well. I know you can't nit-pick but I'd say IBO is well above WBU.
Macklin for me:good. Looking at the others names, I see very good challenges for titles, but you have to assess the current situations and the titlists that they would have to face in their respective divisions as well as their talent. Mitchell's decision to move up to 140 is terrible and I'm pretty sure he'll struggle in the division, which is a crying shame as he's one of my faves and I think he could have made a good fist of it at 130. Clev has a chance at the WBO, IMO, but I don't fancy him to trouble any of the other titleholders at 175 yet.
I'd say Macklin as well. He just needs to stay the **** away from Paul Williams..... against all the other top names in the division he would be a live dog at the very worst.
mitchell or macklin although macklin is fightin sum bum in dublin then euro defence vs pirog so world shot is a while away
