Jim Harbaugh means business.

Bridget Condon of NFL Network reported on the Los Angeles Chargers' first OTAs under their new head coach and pointed out he made a few changes.

"There was no music," she said. "In every other Chargers practice that I've been to before without Jim Harbaugh, they played a lot of music. So that's an interesting note. … [There was an] emphasis on conditioning. The last 10 minutes of practice we watched them do sled pulls. They were doing medicine ball carries."

Condon also pointed out the Chargers didn't hesitate to throw the ball with quarterback Justin Herbert during the practice session, which was notable since Harbaugh's Michigan teams relied so much on the run.

If nothing else, there seems to be a renewed focus on some of the basics without any outside distractions.

Los Angeles was just 5-12 last season, so something of a reset is in order. The roster also looks different with running back Austin Ekeler (Washington Commanders), wide receivers Keenan Allen (Chicago Bears) and Mike Williams (New York Jets), and tight end Gerald Everett (Bears) all elsewhere.

Things figure to look different for the Chargers this season, and focusing on conditioning in particular should come in handy in the fourth quarter in critical AFC West games against the reigning-champion Kansas City Chiefs.

Perhaps if the team improves its conditioning, it may even get to listen to music again in later practices.
