Football Outsiders just updated their advanced WR stats yesterday. They have Jennings as #3 in the NFL right now, Jordy #24, Jones #35, and Driver #78.
Cobb doesn't have enough targets to qualify at this point, needing 5 more. He is listed as the top WR that has less than 15 targets, so expect him to rank well as soon as he qualifies. He would actually already rank #30 in the NFL if they didn't weed out the guys who don't have many targets.
Just kinda confirms what we are all seeing- Our WRs rule, but Driver is not what he used to be. His numbers are all significantly below zero, with zero being what a hypothetical average WR would get in their stats. Ranked one spot above Driver is the only active WR that I know of older than Driver, Derrick Mason. Father Time catches up with everyone.
