I think if the Cubs add guys who project to combine for 8-10 war they will absolutely have a playoff-competitive team. It's pretty clear though that Hoyer is willing to slow-play their ascension and see what the young players produce this year as well. But you get a guy like Clase at the back of your pen and suddenly you have Alzolay as a lockdown setup guy and Counsell to play the matchups (and use Luke Little) - that alone, IMO, could provide a significant swing in the competiveness of the team. Naylor as a 125 bat who wouldn't need a platoon and puts the ball in play, that would be a difference-maker for the offense. It's ok to add great pieces as you go, and not just wait until you think the team is ready to compete.
