In order to get a baseline comparison, you’d need to post the sportsbooks odds as well.  This way, you can run bets for each one and see with which you would have made more money.

45% to win on Brazil is outrageous. Here is what they are implying for each knockout round game:

win round of 16 game: 80.1%
win quarterfinal game: 87.5%
win semifinal game: 81.4%
win final: 78.9%

Wouldn’t that also assume 100% odds of getting out of their group?

Realistically, and without knowing anything about the relative strengths of teams, the maximums should be:
90% out of group
75% round of 16
70% quarters
65% semis
60% finals

That’s 18.5%.  So, that’s what I would think is the best odds you can give any team. 

I guess if you have a huge powerhouse you might have:
95% out of group
80% round of 16
75% quarters
70% semis
65% finals

That’s 26%.

So, 20-25% is the reasonable limit for any team.
