Nah, I wouldn't want Coleman to inherit Hibbo's number, he's already been better than him for a while. All I think of with the number 2 shirt is Moyes' negative tactics and Gary Neville, neither of which are good.
I just think 23 suits Seamus nicely for some reason, probably because I see him as an attacking and exciting player, rather than a defender
Probably also because you're American?
