Richardson's value has obviously dropped with his lousy rookie year and his ACL injury, but I'd still take him ahead of Conley, Montgomery, and any WR who was drafted in round 4 or later this year. (In other words: significantly sooner than where he's going in the
DLF mocks.) He's only worth stashing if you have the room to wait-and-see until late in the season (or ideally until early next season), because of the injury. But looking at his long-term prospects, the main change from a year ago is that he didn't do much with the 500ish snaps that he got as a rookie. The injury, and the fact that Seattle drafted another WR in the 3rd round this year, are pretty minor issues.
