GAA championship: All of the teams, live action and talking points

The championship is here!

It's not even Easter yet, but the championship has officially arrived, and as strange as it is to come this early - we're delighted to sink our teeth into the action. What better place to start than in the Ulster championship, one of the most, if not the only, competitive provincial championship left. Then there's the hurling league final. Follow all the action right here. Antrim take on Armagh in the opening game, and although everything points towards a victory for the Orchard county, the Saffrons aren't without hope. Andy McEntee has endured a difficult start to life in Ulster, but by the end of the league campaign he had Antrim singing off the same sheet, and looking pretty good. Kieran McGeeney however, had one of his most disappointing league campaigns to date, and could do nothing to stop his side from being relegated to Division Two. With their star player Rian O'Neill an injury doubt for the game, and the general mood around the county looking gloom, McEntee might see this as an opportunity to catch them cold. On Sunday we have a real mouthwatering tie between Mayo and Roscommon to kick off the Connacht championship in style. Mayo won the Division One title just one week ago, and would have had zero time to celebrate as they dust themselves down to prepare for this opening tie. Roscommon had a brilliant start to the league, and although they stumbled a little around the middle, they finished strong and ended up in third position, which was way above most people's expectations for them.
