What about... Randall Cobb?

Savvy veteran WR with experience playing in the slot. Knows how to get open, and knows what it takes to be successful in a NFL offense. The stats he put up in Dallas last season would have made a significant impact in the Saints offense. He’ll be 30 next season, but he seems like he’s been around longer than that. I definitely think there’s enough left in the tank to help out during Brees’ farewell tour.
I don't know for sure. Numbers aren't everything, but if you add up the number of targets Ginn and TreQuan got this year (81) it is very similar to how many targets Cobb had (83).

So did Cobb do more with his opportunities than those two? No. Cobb caught 55, Ginn plus Smith caught... 55.

Scheme wise of course, they're totally different players but I see merit in comparing the opportunities players had before anointing them 'better'.
