People keep saying he's a terrible pundit as if pundits are these all knowing bastions of footballing knowledge, if they were, they'd be football managers. they're almost exclusively ex players who don't possess what it takes to manage, they're TV personas there to entertain and attract viewers, some attempt it by attempting to be smart and insightful to varying degrees of success, Neville to his credit is one of the better ones at this and look at his stint in management.
Micah plays the class clown, he does it very very well, he doesn't need to attempt to offer some insightful comment everytime he speaks nor should he. Him laughing at Keane losing it is great entertainment.
