...beat an excellent fighter like Mike McCallum?
I've seen McCallum fight quite a few times, and I've always been very impressed with him. I only ever saw Kalambay fight once, and that was his fight with Nunn. I know Kalambay had a few big wins on his record, but the one over McCallum was his biggest.
If anyone here has seen this fight, can you shed some light on this subject?
