for Baltimore Ravens coach John Harbaugh http://www.billscheapshop.com/cheap-authentic-josh-allen-jersey , who hasn't had that many QBs on his opening day roster since 2009.Now he's got to determine the best way to use them.Joe Flacco will start Sunday against the Buffalo Bills, but Harbaugh isn't revealing whether the backup will be Robert Griffin III or rookie Lamar Jackson.Griffin has 42 games of NFL experience and Jackson is a slick-footed runner who could be a threat near the goal line, as evidenced by his three rushing touchdowns during the preseason.Whether Griffin or Jackson receives spot duty remains to be seen. At this point, Harbaugh isn't even sure how many quarterbacks will be on the active list each week."It won't be any more than three, it won't be less than two," he said with a grin on Monday. "So, we'll see. I really don't know."This much is certain: There's a lot to like about having a former Super Bowl MVP (Flacco) and a pair of Heisman Trophy winners at the most important position on the field."I'm excited to have three quality quarterbacks," Harbaugh said. "It makes our quarterback room stronger. That's really what it does."Griffin went 27 for 41 for 243 yards and two touchdowns this summer. He also proved to very helpful in guiding Jackson through his first NFL camp.Still, Harbaugh said after the preseason finale against the Washington Redskins last week that Griffin's place on the 53-man roster "depends on the rest of the math."After sitting out the Redskins game, Griffin expressed absolutely no anxiety in awaiting the Ravens' decision."When you put in the hard work and you've done everything you possibly can to put your best foot forward and try to show the team that you deserve to be here http://www.billscheapshop.com/cheap-authentic-tre_davious-white-jersey , there's no stress," he said.After the Ravens did the math, Griffin was too good to subtract from the equation."From a team standpoint, you can look at it any kind of number of different ways," Harbaugh said. "There are a lot of factors that were considered, and that was the way it shook out."After going three years without a playoff berth, the Ravens probably can't afford to have a rookie take over if Flacco gets hurt or plays poorly over an extended period of time. Griffin went to the postseason with the Washington Redskins in 2012 and showed during the preseason he can run this offense.Though Jackson showed improvement in each of his five appearances, at this point he's still going through the learning phase. Fortunately, he has two willing teachers in Flacco and Griffin."You can never have enough experience, good guys Youth Kyle Williams Jersey , good people to draw on," Harbaugh said. "He just learns so much from Joe and from Rob."Football Outsiders breaks down Buffalo Bills rookie linebacker Tremaine Edmunds The selection of Wyoming’s Josh Allen with the No. 7 overall pick in the 2018 NFL Draft received plenty of buzz for the Buffalo Bills, but Buffalo’s second first-round pick, linebacker Tremaine Edmunds, has drawn rave reviews with his play in the offseason and through two weeks of the preseason. Edmunds, selected No. 16 out of Virginia Tech, is barely 20 years old. When he steps on the field to make his NFL regular-season debut, Edmunds will be the second-youngest player to ever appear in an NFL game. Edmunds, who was 19 when he was drafted, was the second-youngest player drafted since 1967. He appears in line to start the season as Buffalo’s starting middle linebacker in the heart of defensive coordinator Leslie Frazier’s 4-3 defense. We asked Football Outsiders what gives Edmunds a chance at bucking that trend and excelling as the quarterback of Buffalo’s defense?“I don’t expect Edmunds to be an immediate hit. The tools are raw and obvious White Micah Hyde Jersey , which is why the Bills popped him where they did, but I think the instincts will take some time to develop,” Rivers McCown said. “I think if you’re to believe that he’s good right away, it’s because you have a lot of faith in a coaching staff that churned out good linebackers over and over again in Carolina: Luke Kuechly, Shaq Thompson, and so on.”History doesn’t have many examples of 20-year-old middle linebackers leading their defense. “I think instead you’ll see some splash plays -- the potential is there, and he’s obviously going to make some great things happen -- and you’ll see some lowlight reel stuff,” warned McCown. “You’ll see some blown coverages, some bitten play-actions. Edmunds should be a fine building block in the long-term. I just wouldn’t expect great things instantly.”The Football Outsiders Almanac is available now.
