Well, the SOS (Strenght of Schedule) of BOS and BAL is -0.2 thus far, while TOR is 0.4 (highest in The AL) TBR 0.3 (2nd) and NY 0.2 (3rd).
On the other hand BOS's SRS is the best in the AL, it is 1.4.
Just as Weaver. I remeber fangraphs selling Weaver like a diamond for the next 10 years, 3 years ago or something, and he has never been the same since a couple of years ago.
