For argument's sake - could we not call up both Smeltz and Brockie.
Smeltzy is getting on and hasn't set the world on fire in a while, but he is a known quantity. If we are calling players up based on experience and previous performances (e.g. Fallon), then I'd take Smeltz.
Agree that Brockie is in red hot form, but he has never been a goalscorer for the NT and if he is to play up front, we need him to deliver the goods - and I am just not sure he would do that.
I think Fallon is only being called up for his mana.
Why not just bring him along as a hanger on?
