Look there are two objective truths here.
Objective Truth #1 : When Blanton was brought in, most people were satisfied with the pen. I won't say most people were happy. Most people wanted a lights out closer either Melancon or Jansen, and were disappointed when the Nats got neither. But Blanton made the pen whole. Kelley was very good. Treinen finally pitched well last year. Glover looked to be good. Solis seemed serviceable at the least. That's 4-5 arms. The roles were still undefined but once a closer was found things should shake out.
I define this truth because I'm hearing a lot of "I knew they needed depth! Rizzo didn't do his job!" type of comments and I think that's like 90% hindsight. A few probably did think that, not feeling comfortable with the mix of injury cases and brief successes. A few more probably think everything is always a problem and complained about it while complaining about the offense and the rotation as well. But at the time the majority felt that given the likely contract restrictions keeping him from getting a big money closer, Rizzo did a pretty decent job finding a handful of good arms with potential.
Objective Truth #2 : This isn't working. That the plan might have been ok at the time only matters in saying "Hey, don't blame Rizzo too much"* Congratulations. Now that you've had your cupcake, fix this. Treinen does look broken. A 2.38 WHIP with 10 walks in just over 14 innings? He needs to go to Syracuse to get his head on straight. Blanton does look done. A 1.92 WHIP with 6 homers in 12 innings? He needs to be demoted to last man to see if they can get anything from him. Glover and Kelley should help solve things a little at least but given they are still not back from injury they can't be relied on until probably the end of May.
I keep saying that the NL East is garbage if the Mets aren't healthy and it is. I mean the Nats have gone 4-4 since May started and they've gained 2 games on the Phillies and 2 and a half on the Marlins. But the Mets have gained ground and so have the maybe dead Braves. The longer you let teams stick around the more chance they have of catching you. This bullpen issue is letting teams stick around.
Of course, as we went over yesterday, I don't know how to fix this. A lot of you brought up Turner. I mean, maybe he's growing into a relief role, but I look at his lifetime stats and I don't see anything encouraging. It's not like he's a guy who can dial it up and blow three guys away for you. He's bullpen filler. Move Ross or someone else to the pen has been floated out there too. Voth or Cole are both viable options. Both have some historically decent K-rates. Both are of an age where you'd try to transition them from failed starter. Ross I see less, just because the guy has shown he can be a good starter in the league and he's younger. I guess, I'm saying Cole/Voth into the pen makes sense as the next move. It's leaves you even thinner when it comes to rotation depth but it's not like you liked these guys anyway.** However it looks like Cole is getting the rotation turns so maybe concentrate on Voth now.
Again - like yesterday - any team with a massive failure early in the year is in a bad spot. Teams aren't built to fix big problems early in the year and there usually isn't a good way to do it from the outside through trade or free agency. The Nats have to jury-rig a solution for the next 7 weeks or so. It could stay ugly.
*He has to get some blame, of course, because he picked all these guys. Even if they looked ok, they did fail.
**Sidenote : Have you seen the Nats AAA starter stats? Don't. As for Fedde - he's fine in AA so far but not so great you can project him in the Nats rotation in 2017. He's at least another month in AA and probably the season.
