Definitely some over achievement, so to expect a drop off is not surprising. That being said Tanaka has looked better his last two starts, and having him back to his normal self would really help. Pitching has been surprisingly good. Severino has been fantastic and has peripherals to indicate his ace-like stuff is probably for real. Montgomery has been an awesome call up. The guy pitches very smart, and doesn't throw absolute heat (should avoid elbow issues). He looks like a #3 or at least minimum #4 starter for quite sometime. Bullpen has been so fucking bad, which is shocking with Chapman & Betances.
Although a nice problem to have, with the success of the call ups there is going to be some decisions to be made. Judge will man Right Field for the foreseeable future (or until a potential Harper signing) as he actually has shown a really solid glove. I wouldn't be surprised to see Gardner traded, and maybe possibly Hicks with how great he has been this year. I expect some combination of Hicks, Ellsbury, Judge and one of Frazier/Fowler seeing time next year. Still believe there is a chance Frazier, Mateo and some others get packaged for a front line starter. Gleyber, Gregorious, Castro should start in the field. Sanchez is on his way to superstardom. I still have faith in Bird, but he's gotta get on the field. He has a very talented bat, despite his awful start.
Remember, Yankees have an absolute shit ton of cap space after this offseason, and I still think pairing Judge & Harper is their dream.
