In regard to the bold, just wanted to point out that while you are certainly correct, the first year Josh was playing with the worst group of WR's I think Bills may have ever had. The OL was an issue also, however I don't think the OL was nearly as big of an issue as the down right awful pass catchers were.
2nd year obviously was good improvement, due to upgrade with J. Brown and Beasley. Actually had a couple reliable WR's he could count on. Anyways, just wanted to point out that Murray not only had Hopkins, their WR's were pretty decent outside of Hopkins.
As far as Tua goes, he had a solid group of WR's also. He just wasn't very good last season.
