I don't know how high the price would be for Gallen but he is an interesting trade target.
As far as the end of your blog goes, I don't think we have to suffer through a few "bad" years before we compete again. I also don't think we need to go nuts signing a bunch of expensive FA pitchers to compete. I've said here before, sign Pineda and sign and for 2 more in the same "class and range" as him, pick up 1 or 2 bullpen arms with experience, not expensive closers, Sign or trade for a defensive ss that can hit enough to stay above the mendoza line, and this team will be competitive. Rough estimate 3 starters x 9mil=27 mil + 2 pen x 5mil=10 mil + 6mil ss=43mil. That may actually be a bit high as I think going the trade route with 1 or 2 of those 6 positions would save $.
