Jack has form in that regard. He is definitely a great man to get a team ready to go, but he is not a great lad for plan Bs. I couldn't believe how out-thought he was by Mickey Harte the second time around.
He believes in Kerry football, and he trusts his players to execute the basics well. When that doesn't turn out to be enough, he struggles.
As for being a sore loser, to be honest JAck is a sore winner.
