There's a stat on American Soccer Analysis called Goals Added that basically takes every action a player makes on the ball and assesses how it impacts a team's chances of either scoring or conceding.
Luquinhas ranked 99th in the league in that stat, 38th among wingers/midfielders. On a per 90 basis, he's hanging out in the 130s. There's a lot of room to upgrade from him.
Brian White is first with +.23. Unbelievable. Fucking Thelwell and Struber.
Interestingly, the highest Metro is Duncan at +.11 (minimum 1500 mins). Tolkin is next at +.08. That ranks 4th and 6th for fullbacks. Says a lot about this team!
