I'll throw out some examples, and let you figure it out.
Take 2 different RP. Take a mediocre/average closer and an average set-up/middle reliever, and see what the numbers come out to in this league. A good example would be Braden Looper vs Dan Wheeler. See what the numbers come out to for an entire season. Wheeler gets about double the points. If you want to go one further, take the arguably #1 closer Mariano Rivera with his 7 wins and 43 saves, and compare it to some of the better set-up men. The numbers will probably surprise you.
