Tyndale's Influence on the King James Bible

Can anyone answer a couple of question about the King James Version, that have been nagging me for a while?

I have always heard conflicting views of William Tyndale's influence on the King James Bible. Is the translation practically Tyndale's because the King James translators incorparated his translations of the Old and New Testaments into their work? Or did Tyndale merely lay the verbal groundwork, contributing to the tone and diction of KJV? What's the degree of his influence on the KJV?
