I'll have to disagree with this one, although I entirely get where you're coming from.
Team has shown it can develop starting pitching very well, to a point where we could have a World Series worthy rotation with ample backup at the start of next year. They could and probably should place some of those starters into the bullpen next year as multi-inning high-leverage relievers along with some spot starts - if we have a "bullpen" game next year, I'll feel a LOT more comfortable doing so with guys who can at least piggy-back 3-4 innings each with some success.
With that in mind, the front office must spend and sign players for next year and attempt to get this offense rolling, for the sake of those pitchers (and all of us). So many one and two run losses this year simply because our pitchers have kept us in games.
On top of that, the spending has to occur because they need to give the fans SOME sort of hope for next season. It will be year five of the rebuild with an accidental and lucky playoff run (sorry, guys, I have to call it that at this point). And if not spend, make trades! Use some of that incredible starting pitching depth. That's at such a premium these days, might even be able to do 1-for-1's and get some bats.
Now that the team has more money rolling in from TV and naming rights and other deals coming in along the way, spending has to happen. Fans need a reason to go. The fans will commit to the team if the front office does with sustainability.
I will blame absolutely nobody if they want to jump ship in the offseason if nothing serious happens towards improving this ballclub, and part of that includes the coaching staff. Changes will have to be made. The only coach I would NOT be OK with leaving is Stottlemyre.
