WR the Key?

A friend asserts:

The new NFL is all about wide receivers. Carson Palmer was left for dead 3-4 years ago. Just like Kurt Warner was after his disastrous stint. 
Then they got to throw to Fitzgerald and Boldin/Michael Floyd and others. That makes any QB an All Pro. And it makes defending against the run impossible because you're always going to respect the deep threat. (See Jeff's earlier email about how often the Cards throw deep.)
Go look at Eli's numbers. He's already set a career high in TD passes. Why? Beckham. 
Nick Foles made a Pro Bowl and was a Top 5 MVP candidate in 2013. Why? DeSean Jackson. Where's Foles without DeSean? Benched. 
It's entirely about receivers now. Plain. Simple.
