LOS ANGELES — It is a routine that's anything but routine, Justin Herbert hanging around after most of his teammates have left the practice field to throw more passes.
A perfectionist chasing perfection.
"This guy's out here like an hour and a half after just throwing the same route over and over and over," wide receiver Keenan Allen said. "If it's not a spiral, he'll just keep throwing the same one. It's crazy."
The longest tenured of all the Chargers, Allen was asked about Herbert's predecessor with the team, Philip Rivers.
"Philip never stayed after practice to throw the ball," Allen joked.
Entering his third season and coming off his first Pro Bowl selection, Herbert explained that he likes to put in extra work on any throws that didn't feel quite right in practice.
He said the drills often are more about things like ball placement and stepping forward in the pocket and delivering a strike rather than how tightly the ball is spiraling.
"I think it's just based on whatever happened that day," he said. "If there are a couple throws during practice that maybe I missed or maybe I felt could have been better, after practice is the time to address those.
"I can get as mad or as happy after practice as I want. But, during practice, I need to be level-headed and focused. You can't let the last play affect your next one. So that's kind of the purpose of [doing] that after practice."
The exercise is not unlike a golfer going to the range following a round to work on a certain shot or a specific club.
