Stros are going to fall off a bit. Lots of talent losses, plus the loss of Hinch, is going to to lead to some issues. Plus Verlander is a year older and looked like shit in the World Series. Plus, in the division, Oakland is primed for a breakout year and Anaheim added a bunch of talent. Even still, they're probably a playoff team because that lineup is still stacked, though if their pitching all goes to hell, it might result in quite a drop off.
The idea of stripping the title from them is ludicrous, though. They won it for better or worse. Trying to strip them of it is like trying to say Barry Bonds didn't hit 73 Home Runs in 2001 because he was juiced.
