Been looking forward to this one for a while now
Its actually a first time step up to Light Heavy for Calzaghe slick so technically Hopkins is the one with more experience (although hes only had 2 fights at light heavy I believe so meh). Its all much a do about nothing though, the fact of the matter is its only an extra pound or two and both will be comfortable at the weight for sure.
IMO the odds on unbeaten super champ Calzaghe are great. 1/2 for the straight win or 10/11 on the points decision are the best odds for each at the mo.
I think Hopkins is getting over the hill really. People talk about Calzaghe getting on at 36 but Hopkins is ancient in comparison at 43. I think its important to remember that for all Hopkins unbeaten middleweight glory for over a decade it did all come to an end in 2005, when Jermain Taylor beat him and then beat him again in a rematch, although both were very close points victories. Moved up to light heavy after that and has had 2 wins over decent names in Tarver and Winky Wright. Reality is that Tarver came out of shape to his fight and Wright caught a headbutt (deemed unintentional) that resulted in a big cut in the early rounds.
I cant see how Hopkins will live with Calzaghes hand speed and point scoring ability. In theory Calzaghe should throw twice as many punches and as hes a skilled fighter, any points victory really should be his. So for Hopkins to win hes gona have to stop or KO Calzaghe and I dont see it happening. Calzaghes only been on the canvas once ever and even in that fight he got straight up and knocked the other guy out cos it pissed him off.
The bet value wise is definitely on Calzaghe to win on points. For all the amount I think Calzaghe will win, fact is Hopkins has never lost by KO, only on points decisions. Couple that with Calzaghe seemingly happy to outbox/outscore opponents these days (4 of last 5 fights won on points, the knockout being against the totally crap Manfredo, a nothing fight) and I think its a very good bet. Only problem is when you watch boxing you wana cheer on a guy and hope to see a knockout and that bet goes against that fun element. If I see Calzaghe spark Hopkins and hes sprawled out on the floor I wana enjoy it!
My way around that is to find a couple of new bookies with sign up match bet offers and bet Calzaghe straight win, then use the free bet on the same outcome, to gain double the odds for my money essentially. Only thing to be careful of on that is check the T&Cs cos a lot stipulate you must use the free bet on a greater than evens outcome (which 1/2 on Calzaghe isnt).
The ones I found quickly enough that let you bet anything with their free matched bet are
Totesport £25 (1/2 odds Calzaghe)
Paddypower £25 (2/5 odds Calzaghe)
Boylesports £50 (4/9 odds Calzaghe)
So as long as you dont have those accounts already (or a close friend or family member doesnt

) you could whack on £100 and get a return of £189.44 off that lot, without the disappointment of Calzaghe possibly sparking Hopkins out and leaving your points decison bet as badly broken as Hopkins jaw.
