Froch accomplished more, but I cant help but feel like based on styles it favors Collins. I think he could drag Froch into a tear up, and get the better of things, especially late. Collins by decision, but obviously we're looking at a close fight either way.
Wins over Taylor, Bute, Pascal, and Dirrell, all in their primes. Collins has wins over washed up versions of Benn and Eubank.
