You can use the suggested defense if your players can play it well. Yes he will try to shoot more outside shots, if the coach can get the players to do it. Can you play 1-3-1 against him? Well if your outside skills look atrocious, what good is it? Play that defense if you can do ok, or well.
Sometimes I ignore the strategy. If a team is playing normal or outside, but his jump shots are mediocre, I chose to play inside defense instead. If a team is strong inside defense and you can force the opponent to play more outside, his FG % will be very low. That still wins.
