When the Seahawks offense walked into their first meeting with offensive coordinator Ryan Grubb, most of them were thinking the same thing -- most of them watched just how explosive and pass heavy Grubb's offense was at the University of Washington and came into that meeting with thoughts as to how their offense would look because of it. DK Metcalf was one of the players who came into that first offensive meeting thinking the offense would look like that of Grubb's Washington offense. They would all be surprised to hear the second sentence Grubb said, after saying how happy he was to be there, was 'I know we have explosive players but we're going to run the ball.'

At first, that was not music to Metcalf's ears. "I kind of got mad real quick," he said. But then realized he could benefit from an offense that runs the ball. "The foundation of running the ball first is going to open up everything else for me, Jax [Smith-Njigba], Lock [Tyler Lockett], Noah [Fant] and everybody else in the receiver room and the tight end room."

Last season, the Seahawks ranked 31^st in rushing attempts, and 28^th in rushing yards in the league.

Earlier this offseason in February, Grubb was asked about running more of a rushing offense compared to what he did the year prior, "I think over the course of my career, we've done both certainly," he said. "I think when you look at what we did, probably more specifically at UW over the last two seasons, we were accentuating the positives and there's three receivers that are probably going to get drafted this year, and so I think moving the football through the air was a logical choice and we are going to be a physical team in Seattle. And over the years, that's something that we've certainly done. When the components all matched up, we ran the ball very effectively and I look forward to it. I think that when you have an established run game, it makes calling those other plays, the auxiliary plays off of it a lot easier honestly. It's when you don't have the presence of a run game that things can get really tricky."

And while the receiving room is stacked, and the tight end room is solid, similar to what Grubb had at Washington, Metcalf thinks that their run game is going to be part of the offense's strong suit.

"We're going run the ball downhill and make the defense stop our run first and then after that it's pretty much dealer's choice with how we want to take the game. From there, we can continue to run the ball or push the ball down the field or get singled up on the outside and exploit the corner. So I think it all just starts with the run game and building a foundation from there."

With a running back room of Kenneth Walker III, Zach Charbonnet and Kenny McIntosh, the offense will have their pick of options. Running the ball though doesn't mean that explosive plays are completely out of the picture, in fact those explosive plays are something Metcalf is eager to see.

One of the biggest questions going into Sunday's matchup is what the offense will look like. Throughout training camp and the preseason games, the Seahawks offense didn't show their cards, keeping their scheme on lock until the regular season.

"I know we kept it pretty vanilla during the preseason on both sides of the ball," Metcalf said. "But Grubb is known for his explosive plays down the field, so just looking forward to him opening up a playbook just so we can exploit defenses and push the ball down the field."

On Metcalf's play, head coach Mike Macdonald knows he will be a problem for opposing defenses.

"He's just a beast man. I've told you this, but you have to account for where he is at any given point and we've got a couple guys like that. But DK is definitely at the top of the list on people that can go take it to the house on any play, whether it's a catch or taking the top off the defense. So hopefully Denver has a hard time finding him."

And in terms of preparing for what Denver will bring on Sunday, "I think everything's going to speak for itself."

"Their personnel just fits their scheme," he said. "They will all run to the ball, rally to the ball and they play hard. So we just got to out physical them, outplay them and out hustle them on the offensive side of the ball."
