I think hes confusing Gilchrist with Rod Marsh...who was called Iron Gloves.
People think Gilchrist is a batsman who keeps, hes not, hes a wicketkeeper first and foremost, by his own admission who is extraordinary with the bat aswell.
I dont know much about Geraint Jones, but I have read that he is first and foremost a batsman, who also keeps. Problem was he didnt get any runs so that was useless.
Gilly said that he concentrates on his keeping more than batting, whereas Jones probably wouldve been likely to concentrate on batting slightly more, who knows, just a thought.
Nowadays a keeper has to be able to bat, which is why England have picked batsmen as keepers who can keep a little bit, like Jones, dont know much about Prior.
Anyway to the point, I would pick Gilchrist always over Boucher.
And I have seen Boucher drop absolute sitters, like one off Alan Donald. Donald went around the wicket to a right hander, pushed it across and got an edge, Boucher dropped it, looked up at Donald who was absolutely ropeable, he was furious, then Boucher basically hid in his gloves for a few seconds.
