Basically Monty is banking on the fact that teams shoot a lower percentage from three than they do in the paint.
If they can't hold the other teams to under 34% from 3 it makes no difference. They need to chase teams off the 3, forcing long 2s.
Edit: OP article is flawed. Points per game is not a true barometer of team defense. The Hornets will usually come out well there because they play at one of the slowest paces in the league. TP should be using points per 100 possessions, not ppg. Hornets are tied for 24th by that metric according to Hollinger.
