Thomas brings an edge - Jones
Wales captain Ryan Jones has backed the "all-action" style of Jonathan Thomas to make an impact in Saturday's RBS 6 Nations clash against Scotland.
Ospreys forward Thomas wins his 52nd cap, but it will be his first start at lock since helping Wales smash Japan 98-0 in 2004.
"JT has matured superbly over the last couple of years," said the skipper. "He brings a lot of knowledge and experience, he is very composed and logical at lineout time and he also brings an edge. He is an all-action player, a hell of an athlete, and that is what you need in the Test environment."
