I knew some people, call them the Joneses, who had a cat that disappeared. Nearby the house where the cat dissappeared, lived two bald eagles in a nest made out of sticks. A large bald eagle has a capacity to lift anything that is about ten pounds. Bald eagles can and do kill things larger than ten pounds and then butcher the carcass into chunks that they can fly with. Bald eagles, though preferring fish, eat cats, ducks, and sea gulls when fishing is slow and they fall on hard times. The longstanding assumption with the Jones' cat was that the eagles caught it unawares, and fed it to their chick.
In Alaska, in rural areas, it is customary for homeowners to collect rainwater from their roof into cisterns that are either attached to the house or under the house and built into the foundation. In due time, the Joneses' drinking water which came from their cistern, which was usually crystal clean, (a main benefit of living in Alaska), begain to taste like the water in Dallas or LA. One day, Mr. Jones checked his under house cistern for routine maintenance, and found his missing cat. It had evidently fallen into the cistern and drowned, and had been been putrefacting therein for several months, and he and his family had been drinking it. True story.
The point of this story, if there is one, is that Fernando Rodney's stuff is rotted cat in your drinking water nasty. A player of his ilk would be transformative to this bullpen. The last time the Mariners were a good team, they had three closers, Rhodes, Nelson and Sasaki, with each being nastier than the next. If you made it through Rhodes' fastball, then you had Nellie's frisbee slider, and if you made it through his slider, then you had The Thang, a truly unhittable forkball at the end of the line. The 2004 Angels enjoyed a similar situation with Shields, K-Rod and Percival. Having three legitimate closers does wonders for everything, and all good teams should aspire to acheive this. It seems like all of the good teams do aspire to achieve this.
I suspect that when a bullpen is three closer nasty, then the batters show signs of stress if they haven't scored their runs by the middle innings. This can make the starters more effective. Batters think something along the following line: "I better try to swing for the fences rather than trying to draw a walk. We need runs now, and being passive will not get us there. Also, we don't want to knock the starter out of the game, because the bullpen will come in and we will be even worse off". At least that's what I think they think.
With Wilhelmson, Farquhar and Rodney, you have achieved a state of three closer nasty. This is a near perfected state of baseball being.
