Is led the team to a correct grammar?

"Led the team" is grammatically correct, but it's not a complete sentence. To make it a complete sentence, you need to add a subject and a verb.

Here are some examples:

* She led the team to victory.

* The captain led the team through a difficult season.

* The coach led the team in a rousing cheer.
