I think this paragraph says it all
"The stats paint a clear picture of what the receivers have been dealing with. Through the first three games, Bills receivers caught 78.9% of their targets, including two games of 85%. In the last two games, they caught just 38.8% of their targets, including just 22% against the Texans on Sunday."
