It should be of no surprise to any Yankees fan that Greg Bird will be an important part of the 2018 season, largely because of how he finished the last one. The projections may not show it, and I would imagine your non-Yankees fan friends won’t be drafting him that high in fantasy, but everyone in the know (or, those who know that Bird is the word) understands that Bird is the closest thing to a known sleeper, paradoxical as that sounds.
This is because we know what Bird looks like when he is actually healthy; he’s the same player that hit a game-winning home run against Andrew Miller, and had a 128 wRC+ in the second half and a 151 wRC+ in the postseason.
