I will also say this-- WR talent is the most overrated aspect of team building. Obviously they are important to a degree, and it's an advantage to have great WR's (just like it's an advantage to have great... anything). But they are solidly behind QB, DL, OL, and DB in terms of their relevance to success.
Look at recent SB success-- the most relevant WR's for the winners have been names like Julian Edelman, Nelson Agholor, Alshon Jeffery, Danny Amendola, Emmanuel Sanders, Doug Baldwin, Jermaine Kearse, Anquan Boldin (the 32 year old version), Hakeem Nicks, Mario Manningham...
There are some good names in there to be sure! But no HOF guys, other than Boldin (who was an aged version of himself when the Ravens won their last SB). Not even an All-Pro. Davante Adams is better than every last one of them, and none of those teams' WR corps put the current Packers' group to shame.
Again, I'm all for receiver talent, but it's just not nearly as important as other aspects of team building. You don't need great ones to win.
