Likely, Ron, but I think there's a difference. Drills are all too often empty exercise in a contextual sense.

I feel that the result is that the brain doesn't put the grammar in the correct contextual space. ESLs often memorize irregular verbs in a rote, "break broke broken" manner and they become highly proficient in that but they still often fail to deploy the verbs accurately in a natural language situation.
