Oh, they did stuff, it just wasn't smart stuff. (BTW, redsr, nice summary of the press conference...along with the quotes. In regards to your question...I think someone asked if Mackanin was a candidate to take over full-time...and Krivsky said "absolutely." I don't think from what I heard and saw that he will be the full-time manager but it sounds like he will be a candidate.)
It seems they were caught in the trap of going with aging veterans vs. younger players who have raw potential (I am talking particularly in the bullpen). They should have made the decision to get the younger pitchers experience from the beginning but Jerry and Wayne both like players who are savvy vets and of course play the game the "right way." The plan was disjointed. The bullpen usage patterns were disjointed. Nothing remained consistent from the beginning of the season.
Some quality pieces are in place (Harang, Hamilton, Phillips, Dunn, Edwin and probably even Arroyo), along with talent that could start to break out/improve at any time (Bailey, Coutlangus, McBeth, Salmon, Burton) and even those such as Coffey who could return to their past and play well again. Not all of those pieces might pan out but there are some options there.
What Krivsky needs to work on as we approach the trade deadline (if he has any hope of keeping his job after the end of the season) is looking for quality relievers who MISS BATS. We need some strikeout pitchers in the bullpen. We have a couple who do/have the potential to do that, but they are raw. We need some setup/back of the bullpen pitchers...a few of them...and ones that are MLB ready or as close to that as possible. The pen is full of middle relievers(at best in a couple cases) right now (in their current forms at least...though as I said, a few have the potential to develop into more).
The starting rotation needs work too. Hopefully Narron didn't abuse Arroyo to the point of destroying him and he can return to form and be a solid starter. Perhaps Bailey or Cueto will step up and be a No. 3 starter by next year or at some point within the next couple years. Belisle can fit in at the back of the rotation. But they really need to add a solid middle of the rotation starter, whether that me through a trade or free agency. If that starter takes a couple years or so to make it to the majors, then so be it, as long as we see progress in their development and hope they can help in the future. Castellini might also benefit from spending a little money in the interim to bring in a stopgap, though that is somewhat the strategy that ultimately doomed the team this year. If you are going to try to use stopgaps, at least make them worthwhile ones.
The bench needs a total overhaul too. That can be done without too much pain if Krivsky does things the way he should. We could also use a RH bat in the lineup that gets ON BASE(we struggle with that this year) and can hit it into the gaps.
Not all if the issues will be resolved immediately, but taking care of even some of them as fast as possible should improve the team's record a decent amount if the right manager is in place.
Players such as Weathers, Hatteberg, Conine and as much as I hate to say it...Griffey, need to be on the block. But Krivsky can't move them for just anything. He needs to get legitimate talent. Obviously most of those players will not net No. 1 or No. 2 starters...there are no illusions about that. If he plays his cards right though, Krivsky could cash in those players for several quality bullpen arms and perhaps a solid middle or back of the rotation pitcher that is ready or pretty close to being ready. He has to make smart moves though.
The trade deadline will define Krivsky. He was named the "Amazing Krivsky" when he first took over. If he doesn't get it done at the deadline, he might pull a very fast disappearing act.
