A classic position vs position comparison:
C: Jason Castro/Hank Conger > Bobby Wilson/Chris Gimenez
1B: Mitch Moreland/Mike Napoli > Chris Carter
2B: Jose Altuve >> Rougned Odor
3B: Adrian Beltre (if healthy) >> Luis Valbuena/Jed Lowrie
SS: Carlos Correa >>> Elvis Andrus
LF: Colby Rasmus/Preston Tucker > Josh Hamilton (if fully healthy, this could be flipped)
CF: Carlos Gomez >> Delino Deshields Jr.
RF: George Springer (if healthy) >> Shin-Soo Choo
SP1: Dallas Keuchel > Cole Hamels
SP2: Scott Kazmir > Derek Holland
SP3-SP5: Mike Fiers, Lance McCullers, Collin McHugh >> Yovani Gallardo, Colby Lewis, Martin Perez
Bullpen: Astros >>> Rangers, the Astros are 9th in xFIP, the Rangers are last.
I don't really see how the Rangers are better at all.
