This is going to be a good series, as these teams share almost identical stats. Hamels, Lester, Quintana, Arrieta, Nola and Eflin are all great pitchers, yet each has had some recent struggles. No one ever knows what they'll see out of Darvish, so there's another unknown variable.
Social media is all (mistakenly) hyped up about Darvish vs Arrieta, but I think the games to watch are going to be Eflin vs Quintana, and Nola vs Lester.
