Nope, not buying that. If that were true then (oWAR0 + (dWAR) + (Positional Adjustment) = WAR, and that doesn't work either.
And BTW, if that were true then Mookie Betts would have a whopping WAR of 16.5 prior to the positional adjustment that's just because he plays right field. Now, I like Mookie but I seriously question whether his statistics are worth 16 1/2 wins/year.
Not even 10 seconds of common sense and basic math skills.
