I thought his selection in Georgia was a negative step, a forward plugging a perceived gap on the right. His selection in Germany was a pragmatic step, as we had a rookie full back. His selection in Glasgow was a neutral step, with Keane dropped and Long / Walters selected upfront, Walters more withdrawn I think. I think Walters was the better of the two on the night.
As Junior famously said here last year, there'll always be some huff and puff to Ireland's play so a player like Walters will always have a chance. I actually think he's a good player and I wouldn't judge a selection solely by whether he plays or not. Choice of CB, LB, wide players (if any), Hoolahan or no Hoolahan, central midfield, formation are all factors that I'd consider to be indicative of approach, at least as much as JW being picked or not. And he has a lot of what Long offers, no?
