Such a wide range..... Though the FO deserves the TD aggregate grade of 'A'.....much still comes down to the 'pre-existing conditions' before the off season:
Berrios:More specifically his command of the strike zone....Good hitters were able to watch many of his wipe out pitches spill out of the zone last year and ultimately either run up the pitch count or punish mistakes. 2018 command = potential ACE; No command + associated loss of confidence = as much a bust potential
Buxton: Consistency with the bat; If so = superstar, if not = serviceable defensive specialist
Kepler: evolution to dangerous 3 hitter (yep, that is still his ceiling) vs. stagnant platoon player.
Personally my confidence is Buxton>Kepler>Berrios.I really am still concerned about Berrios.
After this verbal diarrhea:85-77 again with another frustrating loss in the wild card game due to the lack of a true ACE. BUT....I do see 2019 as our true breakout year!
