After seeing Trueblood's article & the Garcia's extension, I'm more optimist with a possible Turang extension. I agree that while Turang is less likely to need guaranteed $ than Garcia, however his skill set (defensive range, base running, league average power) is less likely to receive a huge payday (only 4 2b signed for $100mm+ deals: Semian, Gimenez, Altuve & Marte) at FA at age 31. Gimenez signed at age 23, the other guys were considered better hitters. The Trueblood's estimate looks good for both sides.
PS a Turang extension would be "sick" (using Brice's vernacular).
