The long list is this:
Benjamin, Kerley, Andre Holmes, Deonte Thompson, Robert Foster, McKenzie, Terrell Pryor (lol), Duke Williams, Kumerow, Emanuel Sanders, Crowder, Brown/Beasley (again!!), Tanner Gentry, Harty, Sherfield....
It isn't about how much money was NOT spend on these guys (they are all bottom salary feeders anywhere)--it's that with a roster really in need of WR help perennially, this is the parade that briefly passed through the locker room. They were low/zero impact signings who were usually quickly dumped..
Beasley and Brown were solid pickups. Beasley/Brown 2.0 midseason was beyond bizarre--a desperation move by a GM still struggling to find ball catching weapons.
Now it seems the Bills are going all in on the draft , hoping for a hit at WR, to solve this serious and chronic gap.
