Did he really say that?
I thought he didn't want to play on the European Tour and not being eligible for the Ryder Cup is a consequence of that.
He didn't want to join http://www.golf-monthly.co.uk/news/tour-news/paul-casey-not-eligible-ryder-cup-114367 as you rightly said. He also said he didn't want to play the additional events required as he and his family are settled and he said he didn't agree with the selection process and that he didn't want to play in it. A shame as he's in a decent vein of form at the right time
