For the first time since the final game of the 2019 season, Seahawks fans were back at Lumen Field for the team's mock game practice on Sunday. And while the 15,758 in attendance weren't quite as loud as the 69,000 or so that will be here for the regular-season opener, it was still a welcome site to have 12s back in the building.

In addition to the return of crowd noise to Lumen Field, here are six takeaways from Sunday's mock game, which saw the Blue Team, comprised mostly of starters, beat the Green Team 22-3.

1. Big Man Touchdown!

Poona Ford has become a fan favorite since joining the team as an undrafted free agent in 2018, and on Sunday he made a play that will only further endear him to fans, scooping up a fumble and rumbling 15 yards for a touchdown.

The score was the result of a miscue by the offense, with Geno Smith tossing a pitch to rookie running back Josh Johnson, who wasn't expecting the ball. Johnson tried to fall on the loose ball, but defensive end Aldon Smith dove for the ball at the same time, knocking it free and allowing Ford to pounce for the scoop and score. Needless to say, the fans in attendance, as well as Ford's defensive teammates, were fired up by the play.

"That was fun," Seahawks coach Pete Carroll said. "It was a terrible play by us on offense. The tailback, he didn't know it was a toss for whatever reason, and so we screwed up the exchange right there, but good to see Poona get in the end zone, of course."

2. Russell Wilson deep to DK Metcalf remains a thing of beauty.

The No. 1 offense did plenty of things well, scoring on all four of its full possessions—the fifth saw Russell Wilson take a knee to end the scrimmage—but one play stood out above the rest, with Wilson lofting yet another perfect deep ball down the left sideline, a pass DK Metcalf ran under to catch in stride for a 45-yard gain. That long completion set up the day's only offensive touchdown, a Chris Carson run that gave the gave the Blue Team, featuring the No. 1 offense, an early 7-0 lead.

3. The emphasis on tempo is evident.

While the Seahawks will try to keep as much of their new offense under wraps as possible until the regular season, one word we keep hearing from players and coaches is tempo, and in a game-like setting, it was obvious that Shane Waldron's offense will indeed feature some more up-tempo play. That doesn't mean the Seahawks will be in their 2-minute offense all game long, but Sunday did feature the Seahawks mixing the tempo up at different times and getting out of the huddle and to the line of scrimmage faster.

"I liked the rhythm that we played with. I thought it was really obvious that we were really moving the rhythm and adjusting it as we went," Carroll said. "… We are moving quicker. We worked really hard to develop our sense of tempo so we can change it as we need to."

4. Michael Dickson can still do ridiculous things with a football.

The Seahawks signed Dickson to a multi-year contract extension this offseason, and while most of a punter's work is done off to the side in practice, Sunday gave Dickson a chance to remind folks of why he's one of the NFL's highest paid punters. Punting from just beyond midfield, Dickson hit a low punt away from the returner, and the ball bounced just inside the 10, checked up as if it were a Titleist hit by a lob wedge, then trickled to the 3-yard line, a 55-yard effort with no return.

Not to be outdone by his fellow specialist, kicker Jason Myers, who didn't miss a field goal all of last season, went 4 for 4, including makes from 50 and 44 yards. Myers did, however, miss one extra point.

5. Tre Brown is a physical corner.

Tre Brown is one of the smallest cornerbacks on Seattle's roster, listed at 5-foot-10, 185 pounds, but the rookie out of Oklahoma certainly doesn't play small. With pads going on and with a little bit more contact in the mock game, Brown showed his willingness to put a hit on running backs and receivers. He also made a perfectly timed hit to break up a seem route to Aaron Fuller that would have otherwise gone for a big gain.

"He has not had bad plays," Carroll said of the rookie's camp. "He hasn't had enough turns yet, just opportunities to show the tough situations that he can get in and all that. We're trying to create those as much as possible. We have a number of corners that we're looking at, so the opportunities have been spread over a number of guys, so I don't have good enough information yet; it's going to take a little bit on that evaluation. But how I'm doing it, I'm looking all of his plays, which I keep adding to the plays that he's had, as well as all the guys, are there's plays in there that are bad plays, misreads? He doesn't have that. He's a smart football player. He's been aggressive."

6. The tackle depth is being tested right now.

The Seahawks were without starting left tackle Duane Brown, who continues to sit out practice in camp, as well as tackles Cedric Ogbuehi, Jamarco Jones and Tommy Champion, all of whom are dealing with recent injuries.

That meant a lot of work at left tackle with the No. 1 offense for rookie Stone Forsythe, and while the Seahawks obviously want to get everyone back on the field, Sunday was a good opportunity for the sixth-round pick out of Florida.

"What a great opportunity for him," Carroll said. "A fantastic opportunity for him to get out here. You've got Russ in the huddle and the fellas and all of that. I'm anxious to see how he did. He's been battling the whole time, he's got a really good mentality, he's tough, he's smart. He doesn't say anything, he just wants to know his job and get it done. He's really been a pleasant addition at this point."

As for Brown, who is heading into the final year of the contract extension he signed in 2018, Carroll said. "Duane and I are doing great. In our conversations about stuff, he's been great. He's making a statement about what he feels he needs to have happen."

Asked how soon he needs to see Brown back on the field, Carroll didn't give specific timeline, but did note that regardless of what else was going on, Brown wouldn't be playing in the preseason.
