Ted's flight from Amsterdam took more than 11 hours. He should be exhausted after such a long flight.

It's said "should" is wrong here. "He should be exhausted" can not be expected in this context?

What's the difference between the two should's?
He should be exhausted after such a long flight.
Australia should win this match.


Also,
Isn't "should" used to talk about something that may possibly happen or be true? I feel this usage can be applied to this topic sentence.:-?


Thank you.

It depends on the meaning- if he's not exhausted and this surprises you, then should would make sense.
