(EDIT to add: CHP, I think we were typing simultaneously, so these aren't in response to your last couple posts. And in some cases, I'm echoing what you said.)
I suspect we're not that far apart, CHP. I think it would be fascinating to be a fly on the wall in these management conversations. "Let's do this, unless this happens. But if this and this happens, then let's go here. Because of this, let's consider this possibility. Whoops, such and such just got DFAed elsewhere. Let's grab him and see if he can give us a week until this guy comes off the IL. Crap -- that guy got hurt, so now we have to do this."
Sounds like you have a better handle on the St. Paul guys than me. Are Fitzgerald and Prato significantly better than Clemens, for example? If so, I'd be with you that Clemens wasn't worth signing. I've sorta pictured him as even with them, in which case I was (a little bit) okay with signing him, since it basically just nudged Fitzgerald and Prato one spot down the "I hope we don't have to use him, but he's a breathing body for the future" list.
I think it will be telling to see how Clemens plays into future transactions and how long he lasts. As I mentioned above, it's seemed like the Twins have been more willing to use roster churning on the pitching side than on the hitting side. We're numbed by guys like Margot and Gallo, but they were signed in the offseason with an intentional role on the roster.
We may or may not have agreed with the signing and they may or may not have successfully fulfilled their assigned role. But hanging on to those guys feels different than Clemens. Whatever they are doing now, those guys at some point had some MLB success and there can be some kind of hope (and again, we may not agree on how much hope there was) that they might again.
In Clemens' case (and even Bride's), maybe there have been some, but I can't think of many of these midseason DFA-level pickups, at least those who have overstayed their place on the roster. With Clemens, for example, I think he survived Monday because Julien has stunk, not because Julien had options. If Julien or Miranda or maybe even a Martin -- someone that they've once had confidence in and who's on the 40-man, starts to perform in AAA, I'd hope they would bring him up, even if it means DFAing Clemens. And I'd add that if Fitzgerald or Prato demonstrates a likelihood of outperforming Clemens at some level, I'd say the same. Because of the 40-man issues and no prior record of success, it probably takes a bit more to get the promotion. If one of those happens and they DON'T DFA a crummy Clemens, I'd agree with you in saying they are overplaying that card.
