That works in theory but not in practice given the Cubs farm system right now. I would love to be in that position though, but they haven't exactly had a consistent pipeline of healthy and/or productive starting pitchers in a while. Just look at the health issues Steele, Wicks, Birdsell and Horton have had. Assad has also had issues with health as well, Wiggins is on the IL right now too. They tried to trade for some pitching prospects too and that has not always worked out such as Wesneski and Kilian. Outside of Horton and Steele who was the last starting pitcher to come up through the organization that has been able to stick in the rotation? Let's not forget Alzolay and Marquez in this discussion too as injury riddled prospects that never panned out.Philosophically where I align, and have been this way for years, is that the Cubs should ALWAYS have a paid true Ace and a paid #2, spending $60-70M on both arms. Every other starter should be a team and cost controlled arm.
3-5 years ago, the Cubs were not in a position to do this due to poor organizational planning, hence the Taillon, Shota, Stroman, Rae, Boyd, Davies, Williams, Smyly deals. They were $8-17M deals for #3, 4, and 5 starters because you needed arms as you had none developed.
As books clear, I do foresee the Cubs wanting to be more aligned with my philosophy - Cabrera, Horton, Steele, Birdsell, Wicks, Wiggins being cheap allows for you to get the Skubals and Peraltas. Unfortunately, 4 of those 5 now have serious injuries
