Please Note: I am not including the bullpen in this topic (if that wasn't already obvious).
If you look at WAR, it looks like they are on pace to be the 2nd best of all time. Obviously, they have to keep up the current pace. And if they keep pitching like they have as of late, maybe they will be the best!
The best Reds starting rotation, according to Fangraphs WAR, was the 1982 staff. The 2012 staff is on pace to be just a little bit better than the 1992 staff, which is ranked 2nd all time currently.
Needless to say, it's looking like this staff is one of the best the Reds have had in a very very long time. And can you imagine if Latos comes around and pitches like we hope he will?
