I love Wing Chun. It's what I like to do in my free time.
...but boxing, MT, etc have 'pockets of power' as well. While large looping punches are often seen in boxing - hooks, uppercuts, body shots, etc were developed when the range got closer and straight lines didn't work (opponent covers up, gloves are in the way of their face, etc).
So, yes: Wing Chun would excel in a phone booth, but if you're in there with a boxer, watch your ribcage.
