Uncountable nouns taking singular verbs when they are used as a body or a group

1) The team is at the top in this competition.
2) The team are full of high spirits.

There are certain nouns which take singular verbs when referred as a group or body. A team is probably never divided therefore it is a team. So, in the second sentence are we trying to point out each member of the team and using plural verb?

Also, since each member of the team is of high spirit then collectively its a group/team, so should it not take singular helping verb. Suggestions please.
