Philip Rivers makes his 2018 debut this Saturday night against the Seattle Seahawks.

But let's be honest…we all know what to expect when it comes to the future Hall of Famer.

However, there is a lot on the line for a number of Chargers fighting for a spot on the 53-man roster.

Heading into the second preseason game, Rivers was asked who has caught his eye thus far this summer. Rivers didn't hesitate to offer a few names.

"Gosh, I think Ques (Scott Quessenberry) and the offensive line have done some good things," he said. "We drafted him from UCLA. The receivers, it's been interesting to see those guys. You see (Artavis) Scott. Geremy (Davis) probably wouldn't really appreciate me throwing him in the young guy category, but you just saw the game he had last week and the game Scott had."

Those two wideouts certainly showed out against the Cardinals. Scott had a game-high five receptions for 44 yards while Davis had a game-high 88 receiving yards on four catches, including a ridiculous 47-yard touchdown.

Meanwhile, Rivers was also quick to laud a certain tight end who has received a fair amount of praise in recent days.

"I thought Sean Culkin made some plays last week," he said. "He's really improved. He has gotten an opportunity to get a ton of reps with Hunter (Henry) going down. He's making the most of his opportunity."

So, what's the biggest difference Rivers sees in Culkin's game entering his second year?

"I think more confidence, more reps (and) just more understanding of the offense)," he said. "Playing tight end and also playing receiver — because of how much we move guys around — it's tough because you're the F, Y, what's your motion? At this time, do this. There's a lot, they even play fullback some plays — block power then run down the seam. There's a lot we ask of those guys, so I think it takes them a little time. Sean loves to play. Loves football. He's been working at it and he cares about it. There's something about that — I don't care what level you're in — there's still a big value in people loving ball, and how much it means to them. Those guys usually over time end up being the guys you want to stick around."

Meanwhile, even though he's far from unheralded, number 17 has also been impressed by Mike Pouncey. The former Pro Bowler joined the Bolts this offseason from the Dolphins, and so far has lived up to the hype.

"(He's) been great. I think the in-game stuff is important. We do it out here, the communicating — but in the game, there's just a little more noise, a little more intensity, so that will be good as well. I have no concerns about that. He's been great — both with all the protection stuff, Mike (linebacker) points, and just the way he commands the huddle and runs the thing at the center position. Obviously, you knew of him as a being a Pro Bowl player, but he's certainly lived up to all the expectations we had."
