6. Golden Tate, Detroit Lions wide receiver: Tate topped our list of the best free-agent bargains in early March because he led all NFL receivers in forced missed tackles and yards after catch per reception in Seattle's run-heavy offense last season. The Lions have quickly discovered that his hands are among the most reliable in the league, as Tate has the NFL's best catch rate since 2011. He has been especially impressive in traffic, snagging Matthew Stafford's fastballs in tight windows and evading defenders for extra yards. Tate has carried the offense in Johnson's absence.
