Great thing about a forum. That's why RP generally are throw ins or signed as free agents. Not many times you see a RP as the main focus of a trade..as with the old SNL skit..they're not worthy.
The great ones never get traded because they are too valuable. They also sign 10 and 12 million dollar a year contracts which is more than many starting positional players.
I think that's the key element you're missing in what I present. I am talking about a team heading to the WS with a gap in middle relief. It is the talk around baseball, every writer and media personality is saying the Tiger's Achille's heel is the bullpen. Just last night I heard the ESPN National radio guys doing the HR derby talking about that being the limiting factor.
Which brings me back to my next point of contention for the esteemed posters who disagree that you make a RP the focus of a trade and get the best one for this year's playoff run. Get a closer quality to pitch the 8th inning. He isn't on this roster today. Move Chamberlain to the 7th and you have a pen that you did everything you could to make strong.
Now some (it was said many) disagree with that philosophy. Like Mitch they say "RP doesn't impact a game enough to spend prospects." That comment obviously is incorrect when we look up again at the summary of last year's 8th inning of game 2, but that could be considered an outlier event so I won't harp on it too much.
If we can all agree the soft spot on this team is bullpen, and we can all agree the team lacks talent in the minors. Why would it make sense to try and get a position player and a RP who isn't going to be trusted in October?
To draw an analogy, it is akin to having five dollars and needing eggs. But no, I can't just buy eggs because they aren't important enough. I'll buy a steak even though I have all the steak I need because steaks are more important than eggs. I'll still get eggs but only if I buy steak also.
All of baseball (not speaking for you) believes this team needs another lights out reliever. They talk about it everyday. Why not just go get the best reliever you can? Why muddy the waters?
