Andujar is the worst fielding 3B in the league in his rookie year. Thats very true. Its also very true that the player Andujar is most compared to, Adrian Beltre, was the worst fielding 3B his rookie year as well. He went on to win 5 gold gloves and will likely be a HoFer within 3 years of his eligibility. Not sayin Andjuar is Beltre but players can improve.
Sanchez had a bad year. No doubt. 2016-2017 were great years for him. I won't crucify a young C for a bad year, especially if he bounces back.
Severino has a shoulder problem I think. 2017 and 1/2 of 2018 were terrific. I do not know if Sevy bounces back without surgery, but I would not call him a bust.
"Homegrown" talent, in my view, doesnt just mean drafted talent. It can also mean young and unproven talent acquired from other organizations via trade. That would include Hicks, Didi, Gleybar Torres, Voit and Clint Frazier. All will be contributors this year and for many years beyond.
I do believe Bird will become a good player, but he may need to get out of NY for it to happen. Which is a shame because I thought Bird could have been the best of the bunch.
Judge is simply Judge and a beast.
