I would tend to think that yes more hands become playable again. If the play is a poor postflop calling station and you connect you can gain back with these hands. Also, if he folds postflop if he doesnt connect then bluffs work well and some more hands may be profitable. If he is a strong postflop player then his looseness probably wont allow you to get off with playing more hands profitably.
