This Cubs roster has the feel of some of their rosters during their last rebuild while they were waiting on their impact prospects to make their way to the majors - every offseason they'd go out and sign a few veteran FAs to contracts, and then they'd look to trade them at the deadline 1 to 2 years into the contract for more prospect help. Guys like Bellinger and Mancini are perfect candidates to trade if they have a good first few months of the season. Even Hendricks, Madrigal, Stroman, Hoerner, Happ, Wisdom.
They didn't take the total dumpster firesale rebuild approach this time around, so their organization plan is a bit caught in between. Until they improve their pitching staff, they're not a postseason factor, but they do have an improved roster simply by trying to bring guys in. Plus, at the moment they just don't have the laundry list of "can't miss" (even though several of them actually didn't amount to studs) prospects knocking on the Wrigley Field door in their system. They've got more talent compared to a few seasons ago in the minors, but by and large it's a ways off and there are more question marks with their prospects than when MLB-ready guys like Bryant, Schwarber, etc were in their system right after getting drafted.
