Reduced punch resistance

[VG_Addict]

What exactly causes a fighter's punch resistance to deteriorate, whether with age or after a brutal war? Take for example Pacquiao. He had a strong chin. After he got knocked out by Marquez, he got rocked by Bradley in their rematch.

Its hard to really say, you also have anomalies or exceptions to the rule like Juan Manuel Marquez, this man has taken so many hard beatings, been dropped hard multiple times but still has never been stopped or knocked out cold, and he still speaks perfect Spanish and doesn't slur or have a heavy tongue.

That's not a good example how many WW's caught Pac as clean as JMM and Bradley did?

Concussions.

Medical research has shown after you suffer your first concussion, you're much more likely to be concussed after. We see this a lot in football where a guy has never suffered a concussion get one, then suddenly after that keeps getting them and often from much softer blows than what they sustained prior.

So now apply that to boxing where obviously you get punched in the head repeatedly. You just can't take hard shots anymore.

Take Pacquiao specifically, he was knocked out cold by JMM and most certainly suffered a concussion. He was smart though by taking a year off from fighting (whereas in the NFL they are dumb since they typically only take 1-2 weeks off, granted they aren't getting punched in the head but still), so you can imagine lesser blows are going to effect Pacquiao more than they would have pre-JMM.

Pac is a very mild example. Take guys like Edison Miranda for example or better yet Antoine Echols. Echols was a guy who had never been knocked out before. Went 12 hard rounds with a prime Bernard Hopkins. Then got knocked out by Hopkins in the rematch. He went on to get knocked out 13 more times after that by far lesser opponents and by much weaker shots than he took pre-Hopkins KO. It's sad they let him keep fighting for so long but anyways, this was a result of his concussions. Unfortunately there isn't any way of reversing this. The best thing you can do is take a lot of time off after suffering a concussion, like Pacquiao did. Don't immediately go back in the ring like Roy Jones did against Glen Johnson after getting iced by Tarver. This goes for sparring too, do not take any contact at all for at least 6 months and even then, there is no real way of knowing how long is long enough.

His point wasn't about JMM's punch, it was Pac getting rocked by Bradley after JMM. He's implying that his punch resistance went down after getting iced by JMM. Which is probably true (although I don't really remember him getting rocked myself).

You're correct, though IC was pointing out that the OP's example was a poor one as Bradley caught him with a clean shot and Pac reacted as anyone might. It didn't illustrate decreased punch resistance. I personally think Juanma Lopez is the poster boy for this sort of thing.

That's a good example, although he showed signs of a bad chin especially against Rogers Mtagwa where he was pretty much KO'd on his feet and somehow survived till the end.

Roy Jones is probably the best known example, going from unbeatable superman in 50 fights to getting KOd left and right.

While concussions and brain damage are true, I would also assume that confidence and the psychological side of things comes into play too. You're not nearly as confident in yourself after being knocked out badly

[PivotandRoll]

I think it can be different reasons. For some their brains get damaged and just switch off easier, others are damaged physically and others mentally. Some guys are just ready to lay down once hit.
