Yeah, the thing about Clottey is that when he has the ear muffs on (high guard)...there isn't very much pop on the counters coming back because his arms/upper body are almost never in a position to throw a solid shot from the hips.
I think he is going to try and work behind his jab, but unless he's following up with 2 or 3 punches after that, he's going to be eating a lot of right hooks over the top.
Tough fight regardless, because I seriously don't think Pacquiao can hurt Clottey.
I'm worried because Clottey's main offensive weapon seems to be his head. He uses the headbutt and is very good at making it look unintentional. With Manny being a southpaw, a clash is almost inevitable, and I can see Manny having to fight this one with a huge gash.
