You are choosing a sample size that fits your position, which is fine. 2.5 months is a pretty good sample size, however the point is, we will need a solid #2 RP'er next year that is much better than Kelly is now and maybe the same as Kelly prior to the 2.5 month line.
If we don't replace Kimbrel, in kind, getting a solid set-up man or two takes on more urgency.
BTW, one could argue replacing Kimbrel will be easy, since he has not been doing all that well for ___ weeks.
