Bispings TD defence is up there with the very best I think. Which is just as well as we can't wrestle for **** over here in the UK.
But everyone does consider him top 10 and many people consider him top 5, despite never actually beating a single top 10 fighter since he got brutally KO'd in the division a few years ago. He's closer to being overrated than underrated, clearly.
Bisping and Sonnen could have went either way. The one match which will always hurt Bisping is getting beat by Wandelei who has looked awful since. Bisping is easily a top ten middleweight.
