Quoted from o-din:
I'm still scratching my head how the Chargers managed to contain him in last year's playoff game. They brought a lot of pressure from all different places, and they had the players to do it. But now LJ seems to be able to get rid of the ball as fast as anybody.
Last year was night and day for LJ. Even through the pre-season.. people (including me) seriously doubted if he would improve enough to be a functional passer in the league. He was flight-y, he did not read-defenses pre-snap at all, his pocket presence was poor, his accuracy was bad. When SD changed their personel group, they were able to contain him, the pass rush was successful with only 4 guys, and LJ was still so green he wasn't able to overcome. So when we spent our big draft pick on a flashy reciever... it was like 'why??? we don't throw!'
Then in the offseason... he worked on things and now it's night and day. When he moves in the pocket, its deliberate and into space, he is reading the defense and finding the open routes, his throwing consistency has improved 2x, and the team can now shift on a whim between power running, WR flash, big TE catching, or a running QB.
It's the single most dramatic off-season change I've ever seen. And the guy only started less than half the season in 2018.
Everyone heard the coaches talking about 'changing the game' in the offseason.. but most thought it was bravado ... but little did we know it was the whole staff committing to this scheme. And it's working.
