Chris, I am judging it upon his RC27 score, which is a measure of how many runa a team composed entirely of Francouer would score. His score before tonight was 3.59, easily the lowest for any NL RF.
You could also use OBP to judge this, although I don't think thats fair as it doesn't give a good look at his power numbers.
Lets use a measure known as Adjusted OPS. 71.4% On Base, and 28.6% Slugging (as OBP is about 2.5x more valuable than slugging).
FRANCOUER ON BASE: .257 X 2.5= .643, + SLUG OF .447= 1.0895,
SO HIS ADJUSTED OPS IS .623 (1.0895/ (2/3.5))
Another way to look at it is his.. [SIZE=-1]
Secondary Average (A way to look at a player's extra bases gained, independent of Batting Average)
(TB - H + BB + SB - CS) / AB[/SIZE]
Coming into today, his was .186, the next lowestamong NL Rf's was.204
In summation, the average AAA player would produce similar or better statistics than Mr. Francouer.
