Oh, absolutely
If all star break 2014 this team is out of the playoff picture already it's clearly time to give up. And you could get fantastic returns on guys like Lind, Bautista, Santos and Buerhle at that point from teams on the bubble, with money and holes in their lineups/rotations/bullpens.
If the team contends in 2014, then you keep the majority of these guys and continue to tweak, carefully trading guys away to keep the farm in reasonable shape and filling holes where you need to.
