North has scored 100's in South Africa, India and England probably three of the toughest test teams in their own backyard and has 5 test centuries all away from home, so he is hardly a bottom scrapper.
Yeah, he has been pretty inconsistent and that's one of things he can work on, but hasn't that been the case with most Australian batsmen!? So why just single him or Hussey out!?
Hussey is 35 but don't know why you should hold that against him when it comes to turning his form around or improving, and likes of Laxman, Tendulkar, Ganguly, Chanderpaul, Jayawardene, Mohd Yousuf would also vouch for that.
Also, made my views regarding Khawaja pretty clear, I think he is good player but I have a few reservations over his technique, and though stats show a player's caliber to a large extent but that shouldn't be the only barometer for international selection.
