Did not see that coming. This seems like an odd route for to Google add depth to Plus.
A good example of a lack of depth would be the Indianapolis Colts, who with the loss of Peyton Manning had a dismal, almost winless season.
A good example of a team with a lot of depth would be Ask Ketchum's pokemon. He's got a Charizard, a Butterfree, a Wortortle, a Pidgiotto, and Pikachu. If one of his pokemon gets injured, he has a handful of equally good pokemon suited to other tasks that can fill in.
