Two players peripherals right here-both are on NL Central teams right now, both were on the same team in the years these were taken from, and one is expected to be average while the other one is not: Year 1- A-6.17 K/9, 1.97 K/BB, 2.17 G/F, 1.42 WHIP B-5.27 K/9, 1.69 K/BB, 1.59 G/F, 1.37 WHIP Year 2- A-4.35 K/9, 1.45 K/BB, 1.59 G/F, 1.32 WHIP B-5.28 K/9, 1.81 K/BB, 1.43 G/F, 1.38 WHIP Here is year 3 for one of those 2 pitchers B-4.93 K/9, 1.51 K/BB, 1.61 G/F, 1.45 WHIP Based on those peripherals, what do you think of these two pitchers? Are they both destined to be pretty bad? Where is the third year for the other pitcher? I was going to post that and make a further point after someone evaluated those two on those peripherals that were stated. Is pitcher B better than Pitcher A on those numbers? How much better? Then the obvious answer is the one who has the worse secondary stats. The point that is lost in this not so original example is that every data set has an outlier or two. In other words, just because it happened once or twice doesn't mean it is likely to happen.
