He'll start 2019 with SS in Yahoo, without a doubt, and then probably earn 2B by May 2019 since DJLM is a free agent. From there he just needs to start SS at 5 games when Story is sitting to get it again for 2020, which seems very doable, and/or overtake Story on the depth chart which is also plausible since Story isn't actually good. The Rockies are splitting Rodgers' time in AA across 2B, SS, and 3B right now, sort of the Gleyber Torres deal.
