Let me fill in for him...
He'd probably bring up how baseball & basketball are on every day and nobody complains, completely missing the point that part of the reason the NFL crushes these sports is because it has the advantage of less exposure.
To that point, Thursday Night Football got doubled up in the ratings by Big Bang Theory last week. No more NFL Network clearance excuses either, they are now on every major cable/sat provider.
But remember, people cant get enough and will watch any form of NFL football.
You can't see the effect of overexposure until it's already happening, and then it's too late to reverse because it's like an avalanche. Adding more playoff games would be a dangerous move. They all feel important now. You don't wan't to be the NBA, where early rounds are ignored by the casuals and nobody cares until the Conference Finals.
