In 2014, you MIGHT have King Felix. Seattle is on the upswing a bit, they have a talented young roster and attendance is up. They're not Tampa Bay at the worst of times. This is a team that can spend money to make money, and they're not about to let the centerpiece of the rebuild walk if they can help it. And it would not surprise me one little bit that the Ichiro trade was sparked by a desire to clear out anything that might force them to give up on the king.
That's the problem with projecting any FA 2 years out. The lion's share of them are either re-signed outright, or traded and then signed by the recipient team. Teams don't like letting big names walk for nothing.
As for what they need to do, most of it amounts to the long-term, boring, media-alienating, non-headline-inducing process of drafting, development and promoting from within -- the exact same thing they did to get themselves out of the doldrums in 2006, and the same thing they did to get themselves out of the doldrums in the late 90's. If there's a sure thing out there, sure, go nuts, but the core of every great team is homegrown. Even the Yankees knew that lesson, at least in the Dynasty years.
It might take more than one year. But if you really want this team to be a great one, you're going to need to take it on the chin, get through to the far side of the rebuild, and THEN build AROUND the young core that comes out of The minors. Trying to sign your core never works.
