Yes, Vaz did improve, but he was not a top 8 PA player last year.
Holt was a top 8 player in 2015, so I used him in that comp.
I realize I selected the cutoff of PAs for maximum affect with my argument. One could claim 9 of our top 10 players declined, if I counted Vaz and Beni.
Interesting how the only actual top 10 guy who improved this year was Travis Shaw, who was not managed by JF. Papi retired. Young was 10th and also declined by a lot.
I'm okay with arguing about the reasons for the massive decline, or if JF is to blame for any part of it, but I cannot agree that it was anything less than massive.
Listed in order of 2016 PAs
Betts .897> .803 (-94)
Bogey .802> .746 (-56)
Pedey .825> .760 (-65)
J B J .835> .726 (-109)
Ortiz .1.021>>> retired
HRam .866> .750 (-116)
TShaw .726> Milwaukee (.862 up 136)
Holt .705> . 548 (-157)
Leon .845> .644 (-101)
Young .850> .709 (-141)
Vaz .585> .735 (+150)
Again, the top 8 returning players- by 2016 PAs- declined by more than 55 points!
6 of 8 declined by over 94.
Vaz, at #9 last year went up 150 points. Shaw at #7 went up with another team.
These numbers are frightening. Yes, there are excuses for Holt, Leon, Pedey & HRam, but one still could have done slightly better or much closer to 2016 than they ended up doing. Oh for 4 was probably against the odds. Then, couple that with the fact that all the young guys declined as well, and to me, the word "massive" fits the bill.
(BTW, the next guy, #11 Beni, declined too, but the 2016 sample size was very small.)
