I don't know if you have seen this video,
https://www.youtube.com/watch?v=wboMDwDEVY4It's one channel that I followed in terms of boxing and their video are really great and you know that they really work hard for it.
And with that, yeah, the hype is real, there are tons of videos on Manny's comeback fight and everyone should really be excited although there could be health concern for the 46 year old. But I think he will be ok win or lose in this fight.
The comparison to great players in other sports similar Tom Brady is very much real and very valid, I reckon.
