Other than Floyd, which fighters have retained their speed into their mid-30s?

Everytime I watch that floyd and Chico fight it makes me feel floyd can't be beat

This.

 

Archie Moore at age 45 vs Yvon Durelle was lighting fast,Jersey Joe Walcott was very fast in mid and late 30's,Floyd Patterson very fast combinations vs Ali at age 37,Sonny Liston never very fast but in older ages good reflexes and explosive power,David Tua still fast hands,Dick Tiger...The new science research is that athlete can keep most of the speed and esplosive pover till the age of 45 but he must do special plyometric exercise for that.Between age 20-25 speed is best but after that decline but not rapidly so fighter can be at 45 still very quick if he is discipline and always working on speed.The best example for that is Bernard Hopkins.

 

I don't think he was faster there than against the likes of Gerena, Chico, Vargas, etc...

Though I do think a little of that has to do with him being more deliberate in his combos, pausing for a split second in a combo to maximize accuracy.

 

Roy retained his speed up until about 34 (prime speed or close to it). Floyd should be able to maintain his longer (although he was never as fast as Jones). Floyd's fundamental skills will let him fight longer like Hopkins. Pacquaio is more like Roy in that his amazing physical abilities make him nearly unbeatable, but if he starts to slow down, he will end up like Roy.

 

definitely not impossible, if someone is training for speed there is no reason why they cant actually be faster in their mid 30s.
Its hard to say definitively in boxing if someone is faster than they were in their mid twenties, but to use an example from another sport where speed is measured to illustrate where someone is inarguably faster, linford christie was a faster sprinter at 33-34 than he was in his twenties.
If this is the case for linford then there is no reason why it can't also be possible for an athlete of any other sport

 

SNV was as fast in his 30s as he was in his 20s. When he's 80 he'll have same speed also. I don't think he can get any slower.

Actually, I think Floyd is slowing down faster than everyone think. We won't know for sure until fight night but he did look noticeably slow doing the padwork with Roger. He's still extremely fast but not what he was even in the DLH fight.
