The Justin Herbert-Mike McDaniel pairing has been disastrous.

The Chargers quarterback looks lost through the first five weeks of the season in a new system under McDaniel. Hall of Famer Kurt Warner broke down what he’s seen from Herbert as the Chargers remain winless heading into Week 6.

“Again, this is all speculation here, but when I watch Justin Herbert the last couple weeks drop back and throw the ball right to a defender numerous times, we’re all looking at these plays like what is he looking at? How could he not see that defender that’s right where he threw it? He hit him in the numbers,” Warner said on “The Rich Eisen Show.”

“And I wonder sometimes if that’s Justin not focusing on defenders and looking at his receiver going, ‘OK, I gotta make this throw to the receiver.’ And all of a sudden, as he’s making the throw, the defender is sitting right there because he’s not focusing on defenders and he’s focusing on his receivers.

“Again, speculation but I’ve seen it a lot in pure progression offenses where guys are looking at their guys as opposed to the opposing team’s guys. And they’re a bit oblivious.”
