PECOTA cards

By Tangotiger, 01:45 PM

This is Ryan Howard.  You’ll notice some inconsistencies, which I can only presume is because of the handoff between Nate and Clay.  For example, Howard’s 50th percentile PA forecast is 570, with his 10th to 90th percentile range as 548-594.  The weighted mean forecast is 631 PA.  His Projected Playing Time is 90%, or 640 PA.

His 7-year forecast is interesting.  He is expected to go from a forecast of 631 PA at age 29 to 530 PA at age 35 for a total of 4059 PA.  I don’t know how he gets a bump at age 32.  I have a pretty simple model, and my totals for those 7 years is 4065.  So, weirdly enough, if I start him off at 631 PA, we both end up with identical totals, except mine is a smooth drop, while PECOTA has him bouncing up and down a bit before settling down.  Interesting.

The MORP looks wrong, as it seems to apply the old MORP equation on the new WARP data.  I think.
