Any pitcher could be destroyed by any team. That's not really what you should be basing your opinion on, because then every scenario is a negative one. Liriano has a long track record of success albeit with great volatility from start to start every season. Stroman has experimented with multiple approaches this season, one of which was more successful than the other (arguably I guess), and was one of the best pitchers in the AL this season by multiple metrics.
We have to put someone out there, it won't be Happ or Sanchez, and you don't really want to mess too much with Estrada given his back issues. I think there are strong arguments for both Stroman and Liriano to be given the starting nod, and either of them could completely dominate or get shelled. I just hope the offense (and defense) is there to back them up no matter the outcome and that Gibbons is quick to pull the trigger without sacrificing too many wasted resources (i.e. bringing in any of Happ/Sanchez/Estrada unless absolutely necessary) for the potential ALDS series.
