Key difference between Clarke and Cluxton is the last ten minutes of the All Ireland final. Clarke kicks the ball out when they need to keep it to force a draw whereas Cluxton is centrally involved in seeing out the game under intense pressure.
Granted, the award is based over the entire season (although Barret seems to have got the nod for one standout performance, in the final) and Clarke was busier (good point above about how this isn’t reflected in the fact that Mayo have two fullbacks in the All Star team), the fact that what is generally seen as the most influential player of the modern era hasn’t got one in years is a strange anomaly.
On Moran as POTY. I think it’s deserved. McCarthy is very unlucky, and it must have been a tight call, but Moran kept Mayo in it all year - they could have, and should have, been knocked out in the qualifiers.
All told, Dublin win the All Irelands. All the rest is window dressing.
(Also, good point made in the Irish Times, I think. R O’Carroll was All Star fullback in 2015. Since he left Dublin have had two other All Star fullbacks.)
