Really not sure what Alvarez has done exactly for everyone to think Brook is crazy for calling him out.

The only names on his resume are Baldomir and Ndou and I have no doubt at all that Brook could have beaten them just as easily.

There may be question marks over the quality of Brook's opponents but not in the way he has despatched them.

Brook vs Alvarez is a massively intriguing fight imo. No idea who would win. Nice to see Brook making some noise though.
