Would Mikey beating Spence be the 2nd biggest upset in Boxing history?

No. Not even close. An upset yes but not much of one.

 

nope.

Did you forget about Foreman vs Moorer, Tarver vs Jones, Spinks vs Holmes or Schmeling vs Louis?

 

In history no, but of recent time that would be one of the bigger upset sof the last 10 years or so maybe more.

 

A four weight world champion jumping up an additional two weights and beating the number 2 in the weight cannot be considered the biggest upset of all time. Not even close.

 

Pacquiao beating Oscar is way bigger and that isn't even in the top 10 of all time.

 

No. Not even the biggest upset in 2019.

 

It would be the biggest upset since September when Eggington was beat by Mwakinyo.

For WC title fight it would be the biggest upset since Brook vs Spence.

 

Oscar was a slight favor when the line opened.
In no way was that a bigger upset then if garcia beats Spence.

 

Aren't the odds 8:1?

There were several 10:1 and greater upsets that happened just this past weekend.

It literally would not be among the 20 biggest upsets of the year when 2019 is over.

 

Only because Pac had a huge Asian following to shift the odds closer. In terms of experts views very few picked Pac. http://tss.ib.tv/boxing/articles-of-2008/6182-experts-analyze-de-la-hoya-pacquiao-fight

 

If 4 to 1 is a 'slight favorite ' id like you to be my bookie...

 

No. It wouldn't even be the biggest upset in the past 5 years.

 

I saw anywhere from +120 to +160 in Vegas for pac vs Oscar and I didn’t personally know anybody that thought oscar was gonna win that fight.
We all thought it was suicide.

 

the dude who just beat machado is a bigger upset.
