WAR guide for closers

0-1= minor league closer not the best option.
1-3= Below average closer, probably set up man
3-5= League average closer. 30-35 saves
5-8= above average closer 40-45 saves a year AS
8-= Top closer solid K rate, walk rate, and ERA 50+ saves All Star

This is pretty basic I will probably post examples later but what do you think.
