Would it be smart to back all 4 outsiders in today's CS World Cup matches?

I'm tempted to back Astralis today but H2H looks quite one sided in recent matches.
Maybe I will just wait until the match starts and get involved in-play.
There will surely be some underdog wins today.
Well G2 did not look so good out the gate since Astralis beat them badly on the first map for the first game of the playoffs. So your assumption on Astralis are looking respectful so far even though their past matches didn't do them justice.
Same with Magic they dominated FUT on the first map too for another underdog win. With both the favorites having nearly identical odds pre-match circling around 1.44-1.49x for each of these early matches.
Next are FURIA vs Aurora and GamerLegion vs MOUZ so I can not see the same happening to these favorites in the later matches of the day.
I'm going to bet on this Furia vs. Aurora match. I was analyzing it and everything is very even. This is mainly because even though Furia is in the world's top 3, they are still inconsistent. Furia has a slight advantage in Dust2, Cache, and Inferno, but it's almost equal. Aurora only has an advantage in Anubis. So, depending on the outcome, I believe Furia will ban Anubis and pick Dust2. I'm betting on Furia thinking they will win Dust2 and maybe even Inferno. It's practically a 49/51 for Furia.
As predicted, Furia won, and it was a very close match: Ancient 13-11 for Furia, Nuke 14-16 for Aurora, and Mirage 13-9 for Furia. And a detail about that Mirage map: Furia finished the first half 3-9, meaning they were losing. However, in the second half, they won 10 rounds in a row and closed out the match. It was incredible to watch!
In addition, Vitality and Spirit won, as I also mentioned here. And I still believe that Spirit will win the match between the two teams.
Fura is currently playing against G2 and just won the first map. I'm still betting on Furia's victory, even with the lower odds.
