I think people have to find a middle ground here, obviously it makes no sense to keep relievers at their highest value when some team could potentially give us a solid player in return for them, just about anyone in the org can replace them. Then there's this idea that people get that relievers are going to get us a team's best prospect, nothing is set in stone, I could still be wrong, but teams value their top prospects just as much as anyone and for obvious reasons. You trade these relievers for any kind of valuable piece that you might get back, seeing as they are easily replaceable, but people should not be disappointed because the return player isn't a 5 WAR 3B under team control, or some team's best prospect, that just isn't happening.
