With the new draft lottery rules the Jays wouldn't be able to get a lottery pick 2 years in a row so in a way it makes tearing down/doing a full rebuild less advantageous. And with the expanded playoffs teams are probably saying well we may as well try to sneak into the postseason. I understand the idea of selling high on a lot of players though given the impeding FA in next 2 years (vladdy, bo, gauseman, bassit, berrios, kirk)
The system actually seems to be doing a good job of making teams try to be more competitive.
