Eight teams in NFL history have rostered five players who — at some point in their career — gained at least 1,000 receiving yards in a season. The most recent three teams were the 2003-2005 Rams, who had Torry Holt, Isaac Bruce, Marshall Faulk, Kevin Curtis, and Mike Furrey. Furrey wouldn’t record 1,000 yards until he joined the Lions in 2006, while Curtis’ only 1,000-yard season came in 2007 with the Eagles. But they qualify, as the question doesn’t concern itself with when that 1,000-yard season occurred.
As this question is, well, impossible, I’ll simply list the players from “least useful” to “most useful” in terms of guessing the team and year. Post in the comments after which player you figured it out!
