If you do that, it might fail; I tried it on Ubuntu 12.04 with a Zydas-based Belkin USB stick and it got
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Device or resource busy.
I don't know if that's NetworkManager getting in the way or not.

airmon-ng is my recommendation in these cases. It has a large bag of tricks for dealing with the twisty little maze of Wi-Fi drivers on Linux, many different (although I think mac80211 drivers would all be treated the same; airmon-ng handles that).
