True. Bills receivers average depth per reception since Josh has been under center is not far off that of the game’s best receivers.
Probably the difference in quality/production is attributable to scheme, targets and YAC (except for Shakir). But although you dont need to run go routes and post patterns all day you do need to be able to credibly run deep routes successfully on occasion IMO so that the risk has to be accounted for by the opposing secondary. Maybe thats a large part of what a Chase, Lamb, Tyreek, Jefferson etc… actually do for you.
Bills passing attack basically takes what the opposition appears to give you. But what seems to be intentionally given can sometimes more easily be taken away (see NE Patriots) so sometimes you need to be able to take what they dont want to give you. Bills dont seem to do much of that.
I dont buy the argument that the problem is Josh’s long ball inaccuracy. He’s thrown many long balls laterally as deep outs and he has shown that he can do so with the necessary arc and touch- witness his game breaking toss to Palmer to beat the Ravens. He just needs to do more of that between the numbers.
