Pollard is playing with a double-edged sword with this move. We won't know if his plan works until next season most likely. If/When he does the same for the Nebraska game, we'll see how many more season ticket sales there are compared to this year when everyone is trying to see who will flinch first, JP or the fans holding out on season tickets.
Sticking to your word is one thing...but leaving 15,000-20,000 empty seats for the Iowa game will be a mistake IMO. That is $1 million of easy money...to leave that on the table would be bad.
