Not everyone is cut out for 3 full sedarim a day. The OP could just as easily have asked about the bachur who has a chavrusah for 90 minutes after davening, goes to work, and has a chavrusah again later in the evening but is not officially enrolled in any yeshiva.
A smart girl (or her mother or father or whoever it is that vettes shidduch suggestions for her) should at least consider such a boy and not dismiss him out of hand.
