Worst undercards to Boxing's biggest PPV'S?

Mayweather vs Pacquiao undercard was pure ****.
Santa Cruz and Lomachencko could have fought each other but they wasted money on having them fight bums and it did nothing for their popularity.

There was a time where guys took advantage of the lime light on undercards and scored big wins or looked impressive. That took the cake for the shittest undercard ever next to Canelo vs Smith.

 

Pac vs delahoya

I think they all ended in 1 round

 

Pac vs Marquez 4

 

There seems to be a pattern of Pacquiao fights having shitty undercards.

 

I like seeing that kid related to Oscar,he looks good but the Rosado fight was awful,makes me laugh though does Gabe every time I see him being interviewed in a Gym by Sechbac,it's like he's no idea he's ever lost before lol?

 

I think big fights are somewhat doomed to fail because all the money goes to the main event fighters. The success rest mainly on the main event. There's not a lot left to grease the undercard.
