The Chargers Day 2 picks, wide receiver Tre’ Harris and defensive tackle Jamaree Caldwell, have played a big part in the season as well even if the numbers aren't big. Both rookies have played in all eight games, with Harris starting four of them and Caldwell starting three.
And for Harris, the early portion of his rookie season hasn't been flashy, but his dirty work as a blocker has turned heads in the building.
The second-round pick has repeatedly seen a lot of action even when he's not catching the ball, as he has been a difference maker for the Chargers in the run game.
He's come along strong as a pass catcher as well, as six of his 11 receptions so far this season have gone for first downs. And he caught his first NFL touchdown in Week 8.
"We knew he was tough, you could see that on the college tape, but he's exceeded expectations," Harbaugh said. "The better they do, the more they get, the more they earn. You can see it building and building for him.
"He's just a football player and that's the best definition you can give someone," Harbaugh added.
The same can be said about Caldwell, who leads all Chargers defensive linemen in defensive snaps through the first eight weeks.
The No. 86 overall pick in the draft has seen a lot of action, especially as the unit has battled through injuries of late, taking on double teams and doing a lot on the interior.
Still, Caldwell ranks 16th among all rookie defenders and fourth among rookie defensive linemen in splash play rate (6.8 percent), according to The Athletic.
"He's getting pass rush production, he's playing well against the run," Chargers Defensive Coordinator Jesse Minter said earlier in the year. "He's what we hoped he would be going back to the draft and he certainly hasn't disappointed."
"He's a big guy that can hold up really well in the run game and be dominant at the point of attack and take on double teams and single blocks," Minter added. "Then he also has an element of twitch that a lot of guys his size don't have and some pass rush knack."
