In addition to the meaning of the phrasal verb “to keep off”, there is the idiomatic expression “to keep off the streets”, which means to keep (someone) out of trouble. Trouble can be found out in the city when wandering the streets. Dr. Krashen uses this in his humorous style to mean that he kept his rival busy, as when someone is too busy to get into mischief.
