I think the reason why Rodgers and Nelson are the best QB/WR combo in the NFL is not only the last TD, but the TD in the back of endzone. Jordy didn't just run around trying to get open, he recognized the open space in the coverage, exploited it, and Rodgers was aware enough to hit him. Having a QB who is savvy and aware enough to exploit your weaknesses is hard enough to defend, but throw in there a WR who can perfectly adjust on the fly and that WR being 100% on the same page with that QB and it's impossible to defend...that's not even mentioning Cobb who is very savvy and aware himself. If we had an athletic veteran TE who could exploit weaknesses then this offense would be completely unstoppable.
Defenses have to get to Rodgers in under 3 seconds if they want any chance of stopping him. That means the DT/DE/OLB better immediately flatback the Tackle or Guard and hit Rodgers while the DBs are sharp and on their game.
