You are not paying a licensing fee each year. You paid that at the time you purchased the PSL. The yearly gee is a ticket purchase.
I could see us in a situation where we paid for the tickets and then the amount was credited toward the following year's tickets.
Still would suck because you would be out your cash for a full year. I bet there would be a legal remedy if they tried this.
PSL owners would still have to pay for there tickets. As I said, the owners will proceed forward with football going on without a CBA in place. The players would have to choose to go on strike. Just like the networks, really the only way they could recoup any money lost would be to sue the NFLPA.
With that being said, I doubt any owner will force their PSL owners to pay for games not played without some type of reimbursment. That's just too much bad PR. But I wouldn't count out this situation going to the point where you are paying regular priced tickets to watch a bunch of replacements playing.
