Assuming the work the Dodgers did to "fix" the Heandog isn't just a one off, that's a mighty fine looking rotation they got.
DeGrom, Perez, Gray, Heaney and then potentially Jack Leiter or Kumar Rocker to fill the fifth spot if they show something in spring training.
Texas is just a couple bullpen arms away from being a playoff team. (not a contender, but at least good enough to fight for a spot)
