Second Captains are the standard bearer in Ireland in my opinion and would give particular praise to Richie Sadliers' series of interviews called 'The Players Chair' as he gets a range of guests from all different sports. I find podcasts a great way to learn about other sports and niche topics too that the mainstream media don't always cover.
They are by no means perfect but if you are after something more GAA focused, we've done 19 one-on-one interviews with GAA players on the Real Talks podcast now. They usually last for an hour or so and focus on sport, life, passions and life outside the sporting bubble - we just tried to show a different side to GAA players. Kevin McManamon, Eamon McGee, Oisin McConville, Brendan Maher, Cora Staunton and Philly McMahon have been the most popular episodes so far. If interested, you can find them at RealTalks.ie or search 'Real Talks' into your podcast app.
