Hi Gus,
It depends on what you're looking for when you consider it a "good fight".
If a good fight means non-stop action, going toe to toe and slugging it out, then yes, this was a good fight. If a good fight means the fight was evenly matched, then no, it wasn't a good fight, because Lacy just kept missing (which is a testament to Calzhage's defense, of course). Near the end I switched over to HBO's rebroadcast of the Mosley-Vargas fight, so I never caught the final scorecards. Did Lacy win any rounds? I doubt it.
I found the Mosley-Vargas fight to be far more interesting, because it was so even. The judges were split, all with one-point margins, at the time it was stopped in the tenth. They said ringside observers had it 6-3 and 7-2 for Mosley, but I couldn't see how. There weren't as many power punches landed as in Calzaghe-Lacy, but at least they were more evenly distributed between the two fighters.
