Daddy, I LOVE your flow-chart! (I haven't studied it yet, but I love the concept. I'll give it a good luck tonight.)
As you are a Mariners fan, like me, and you want to be able to watch your favorite team- you missed the one solution that would allow you to avoid paying for cable while retaining access through this "M's Season of Destiny" (in February, every season is the Season of Destiny"!) Move to New England! (Or San Francisco, or Texas, or...) Alaska could be another choice- just for the season; back to Seattle for the winter, when broadcast rights don't matter so much.
Seriously- it does seem perverse that a league that encourages us to support our hometown team would charge double for the chance to watch them play... even on the road! I though the NFL had a corner on every opportunity to squeeze dollars out of fans- but this one bears challenging, asking them to justify how this encourages fans to support their local ballclub.
Finally- if moving regions of the country is not an option for you and Mommy-O- I get a lot of satisfaction supporting the players who haven't yet touched the major leagues, down in Tacoma, or even the players who are just joining the majors for the first time, up in Everett. And it's a lot more cost-effective, if you want to attend more than 1-2 games a season!
