Using the RC sabermetric formula on the ESPN MLB stats site (Runs created = [(H + BB + HBP - CS - GIDP) times (Total bases + .26[bB - IBB + HBP] + .52[sH + SF + SB])] divided by (AB + BB + HBP + SH+ SF)), Drew created 91.6 runs for the Sox in 2009, which was 11th in MLB for right fielders, behind Choo, Suzuki, Werth, Ethier, Markakis, Abreu, Upton, Cuddyer, Hawpe and Swisher. Using this method, 9 JD Drews would create 824 runs (9x91.6=824) in 2009. In 2008, Drew created 79.0 RC runs, which was 16th among RFers, behind Markakis, Ludwick, Suzuki, Abreu, Dye, Giles, Ethier, Bradley, Winn, Nady, Ordonez, Hawpe, Pence, Hart and Werth. 9x79.0=711. In 2007, Drew created 76.1 RC runs, 14th among RFers behind Ordonez, Suzuki, Markakis, Hawpe, Abreu, Swisher, Hart, Francoeur, Winn, Guillen, Kearns, Cuddyer and Pence. 9x76.1=685. The three year average is 82.2, which would total an average of 740 runs created per year for 9 JD Drews.
The Red Sox as a team scored 872 runs this year, 845 runs in 2008 and 867 runs in 2007. That's a three year average of 861 runs.
So 9 JD Drews would create an average of 740 runs a season, which is 16% less than the number of runs the Sox actually scored, according to the sabermetric formula used by ESPN.
