As to the original assertion of Quentin being bad, yes, he isn't good. But a RF has to be historically bad, to realistically affect a teams' run prevention in any tangible way. I'm not going to approach Hawk-level enthusiasm, but the Sock are good at the critical positions of SS, 3B, CF, and at least average in LF, 2B, 1B.
Look at what rivals Detroit and Minnesota are running out there. Tigers have a couple decent defenders in CF Austin Jackson and 3B Inge... and total nightmares at virtually every other position. Ordonez, Pheralta at short
, Miggy at first, who knows what at 2b (Guillen, who is terrible with the glove), unknowns in left.. and VMart at C, who posssibly makes AJ look proficient at throwing out runners...
Even the vaunted "fundamental" Twins have 1 ok outfielder in Span, terrible corner outfield defense in Young/Kubel/Cuddyer, unknown up the middle with Casilla (book on him is lazy) and a Japanese import (not good precedents there... unless you loved the Kaz Matsui era) and I don't think Morneau, Valencia, Mauer, et al are known for their gloves...
