With the most popular projection systems being ZiPS and Steamer, I'm wondering just how reliable are these formulas? I've found with young and old players the projections can get a bit wonky. These formulas are a best guess using the intelligence and historical data available but nobody would admit them to be near perfect. Here's a three examples of projections that are looking pretty off:
Brad Miller - 24 y.o. Great milb stats and performed well in 1/2 of 2013, but has faltered and shown no real signs of improvement in 2014, BABIP is low but consistently.
Current 2014 wRC+: 34
Projected 2014 wRC+: 90 and 97 (ZiPS and Steamer RoS, respectively)
Alfonso Soriano - 38 y.o. BABIP and other peripheral stats pretty normal, just not performing as well as expected.
Current 2014 wRC+: 78
Projected 2014 wRC+: 105 and 90 (ZiPS and Steamer RoS, respectively)
Joe Nathan - 39 y.o. K's are down, BB's are up, BABIP is lower than average, velocity down about 1 mph
Current 2014 FIP: 4.82
Projected 2014 FIP: 3.42 and 3.19 (ZiPS and Steamer RoS, respectively)
