Rodgers never could win on his own. Neither could Marino. The 2010 team had a lot of talent. Look at Mahomes, he has weapons all around him. All that talk about how SF would regret not drafting him. But GB has not put the pieces around him, who has let down who? The last two NFCCGs we've been badly outclassed, we haven't had the horses.
Rodgers has lost a step, but he's still a good quarterback. But we're not getting a Super Bowl win if we don't get the parts. Whether or not we can do that remains to be seen.
In that regard, yes, Rodgers had a hell of a receiving corp. Driver, Jennings, Nelson, Jones, Cobb(circa 2011)etc.
ASIDE from all the other factors that decide a game's outcome, I think Rodgers came to a stumbling block and had to come to terms that his elite receiving corp came to an end when Nelson left. I really think Nelson was a major factor and gave Rodgers confidence in that receiving corp he had from 2009 and on. You noticed the great chemistry the two had on the field. He just knew where Nelson was and it was magic. Once Nelson left I could only sense a deflated Rodgers and he really did what he could with Adams' and company.
Hopefully Rodgers, before his retirement, does get another gifted receiver to work with along side adams.
