Gilly is a Legend! He was awesome behind the stumps and in front of them!
As stated earlier, Prior is a quality bat with an excellent Test average of 42 from 59 matches, which is World Class by any standard. Where he has improved is with the gloves!
I rate him as the best Test keeper/batsman at the moment and his form over the past 2 years (with bat and gloves) has been excellent and probably should have earned him a go in all other formats.
If Gilly hadn't of rewrote the book on what a keeper should be, we would probably have Foster behind the stumps for England!

Nothing wrong with Foster - his batting would not be the best at International level but I rate him as the best gloveman full stop!!!
Gilly - There are better batsmen (Sanga) and better keepers (Foster) but better keeper/batsmen/cricketer? Not yet...and not likely for a long while either!!
