The 2018 season for the Phillies is an incredibly important year for the rebuilding process. Between Hoskins, Crawford, and Alfaro, the young core has to take a step forward if they want to compete. They have some veteran leadership with the addition of Carlos Santana which could help with a late playoff push.
The biggest concern going into the year is the pitching staff. Nola looks like he could be the workhorse they need but you need consistent performances out of Velasquez, Eickhoff, and the rest of the staff.
Overall, the core is there so the idea of a playoff run isn’t to far fetch. It depends on the consistency of everyone over a 162 game season. If you get that then you have a successful season.
