Revamping the offensive line has become an annual rite

of spring in Denver.This time Denver Broncos Hats , it appears to be paying off.Rediscovering a balance that was elusive almost all last season, the Broncos rushed for 146 yards — all but four of those from rookies Phillip Lindsay and Royce Freeman — and passed for 329 yards in their 27-24 win over Seattle . The Broncos' 470 yards of offense were their most since Peyton Manning retired after the 2015 season.It all started up front, where all five O-linemen played all 74 snaps and drew zero penalty flags."Offensive line was incredible," said quarterback Case Keenum, who was sacked just once. "It was awesome to watch those guys. There were some plays where I had so much time in the pocket. I'm going to be so excited to watch the film and see those guys play."The Broncos allowed a whopping 52 sacks last season, an average of more than three a game, prompting them to make several changes in the offseason.Coach Vance Joseph replaced O-line coach Jeff Davidson with two coaches, one (Chris Strausser) to focus on the tackles and another (Sean Kugler) to tutor the centers and guards.General manager John Elway jettisoned oft-injured Menelik Watson despite a nearly $7 million salary cap hit and traded for ninth-year right tackle Jared Veldheer.They moved guard Ron Leary back to his natural left side, making room for Connor McGovern, their strongest lineman, on the right side and giving a big assist to second-year left tackle Garett Bolles.And their anchor — center Matt Paradis — participated in the entire offseason program for the first time since college after undergoing double hip surgery two summers ago.The tackles didn't commit a single penalty, something that was a common occurrence last season."Jared played really well and Bolles did some good things. He blocked his guy. He's got a couple of mental things he's got to clean up, but as far as tackles, we played really well," Joseph said. "We had one sack and the one sack was on the quick game and the ball should have probably been in the flat."So, offensive line-wise, I've been really, really pleased from preseason until now how they've played in the run game and the pass game," Joseph said. "And that's the key. If we're going to win games and keep Case clean and help Case play better and better each week we've got to run the football and protect Case."So far, so good with those guys playing so well for us."One thing the Broncos are doing to help Bolles Denver Broncos Hoodie , an athletic but raw tackle who only played one season of major college football at Utah, is not setting up so deep. That allows him to better use his athleticism to counter edge rushers, who don't have as much of a running start, either."He's a long, athletic tackle, so we're coaching him to set quicker and not give as much ground, to use his quickness on guys," Joseph said. "If you're facing a great rusher and you give him space, he can bull (rush you), he can get around you. So, we're getting Garett on guys quicker, so he can use his feet and his great quickness to stay in front of guys and that's preventing him from being so soft in the pocket like he was last year."So, that's more about Chris Strausser and Sean Kugler coaching him differently this year. And having Leary next to him, obviously the mental part of the game, it helps having a veteran next to you. So, I've been pleased with the entire offensive line. They're playing good right now and hopefully we can continue to play good there."Bolles said playing next to Leary is a godsend and getting instruction from the two-coach system has helped him take a big jump from his flag-filled rookie season."I'm excited to see where this goes because we're right on track and we're headed in a good direction," Bolles said.That said, he's not about to start celebrating after just one game, no matter how clean."I mean, it's a clean game but it's only Game 1. We've got 15 other games we've got to go through Customized Denver Broncos Jerseys ," Bolles said. "There's some things we have to fix, but a fast start in a season is always a good thing. We made a baseline where we're at and we know where we need to go."I have a great group of dudes. The O-line room is special. This team is special and we're going to go in the right direction as long as we put in the work and the effort, which we are."Notes: The Broncos waived WR/KR Isaiah McKenzie on Monday but didn't make a corresponding move, leaving their active roster at 52 players. They did make room on their practice squad for WR Carlos Henderson by releasing WR River Cracraft. Henderson had been suspended for the first week of the season following a marijuana arrest over the winter.Case Keenum focused on taking care of the football on Sunday Trevor Siemian was never asked to do anything too risky in 2016 and the Denver Broncos offense finished with the most three and outs, but Siemian had 3400 yards with an 18-10 touchdown to interception ratio. That conservative mentality changed in 2017 and more pressure was put on Siemian, Brock Osweiler, and Paxton Lynch who all then became a turnover machines. The Broncos didn’t lead the league in three and outs, but the turnovers were leading to blowout losses.That is the delicate balancing act new Broncos starter Case Keenum must follow heading into this season. You can’t win games if you don’t score points and you can’t score points in the NFL if you don’t take some risks. Keenum seems to understand that. He noted the importance of taking care of the football, but also the need for points in this league.“It’s different every week depending on the gameplan and depending on what the points of emphasis are from V.J. (Vance Joseph) and Billy (Bill Musgrave) and those guys,” Keenum said of game planning. “Obviously, taking care of the football and staying on the field. Getting first downs and getting touchdowns. You’ve got to score points in this league to win and you’ve got to take care of the football, especially against a team like Seattle.”The best way a quarterback can be successful is to have a strong rushing attack behind him. That is one area the Broncos seemed to have gotten a heck of a lot better at in just a single draft with the addition of third-round pick Royce Freeman and undrafted rookie Phillip Lindsay.Freeman has already been named the starter and there is near universal praise for what Lindsay is going to be able to do to opposing defenses in space.“We’ve got coaches coming up with a great gameplan as far as running and passing,” Keenum said. “They’ve always, historically, been a really good defense against the run—very stingy. They like to play a lot of guys down low and stop the run. They do a good job getting in their spots that they drop to or if they play man. Zone or man, they are good at covering the pass. It’s going to be tough. We have to establish the run and be able to throw the ball too.”How the Broncos rushing attack performs in Week 1 will go a long way in determining how successful this offense will be this season. Keenum sees it that way too, because picking up a first down on a third and two is a lot different than trying to do it from a third and eight.
