Ranking starting quarterbacks is a popular, fun and, ultimately, imperfect exercise. What do you value most? The consistency of ? The playmaking of ? The athleticism of ? The arm talent of ? The dual-threat ability of ? There's no perfect answer.It's even more muddled when ranking backup Dominique Wilkins Jersey quarterbacks. How do you value the starting experience of or against the physical tools of or ?How about combining starters and backups to rank the best quarterback rooms as a whole? There is no perfect way to do this, but we can look at some numbers. Overall last season, Week 1 starting quarterbacks played roughly 79% of their team's offensive snaps (not including kneel downs and any formations where there was no "quarterback" on the field, like wildcat). So we can a sign starter ranking 79% of the weight and backup ranking 21% of the weight. Like I said, it's not perfect, but at least there's reasoning behind it.Having a top-tier starter, of course, is far more important than having a top-tier backup, just like at any other position. Last season, the ' Week 1 starter, , played 99.7% (1,109 of 1,112) of the snaps in these situations. It didn't really matter who the Chargers' backup quarterback was to take those other three snaps. On the other hand, Washington got just 15 snaps out of Week 1 starter before his season-ending hip injury. While it's always going to be hard to survive playing so much without your starter, was a solid backup, nothing more, nothing le s -- Washington's 7-10 record reflected that.Yes, this formula probably shortchanges a team like the , who have Brady -- not only an excellent player but one who hasn't mi sed a game due to injury since 2008 -- and a le s-than-ideal backup situation that hasn't really mattered. Hence, I told our rankers to rank their starters "in order of who you would want leading your team for an entire season while taking into account potential injury concerns." Similarly, I told them to rank backups "in order of who you would want leading your team for several games if the starter mi sed time." Think 2017 . The had a terrific backup, and he led them an improbable title. It's an extreme example, but try telling the Philadelphia faithful that backup quarterbacks don't matter.So, eight voters, including CBS Sports writers, editors and researchers, ranked the starting quarterback situations and the backup quarterback situations. I then used the formula above Wes Iwundu Jersey -- giving starter ranking 79% of the weight and backup ranking 21% -- to generate overall quarterback room rankings. For example, Patrick Mahomes was the top-ranked starter, so he earned 25.3 points (32 multiplied by .79). His backup, , finished 22nd among backups, so he earned 2.3 points (11 multiplied by .21). Overall, that put the at third with 27.6 points, as you'll see below.(RANKERS: Zach Pereles, Jordan Dajani, Kevin Steimle, Cody Benjamin, Doug Clawson, Josh Edwards, Tyler Sullivan, Jared Dubin)TeamScoreStarter (rank)Backup (rank)1. 28.7Aaron Rodgers (2nd) (13th)2. 28.3Josh Allen (3rd) (11th)3.

Shakeup at the Khem Birch Jersey topEach of the top seven starters saw their teams finish in the top seven of the quarterback room rankings. Again, starters matter most. But it was interesting to see voters' feelings toward Packers backup Jordan Love and Bills backup Case Keenum push those teams over the Chiefs' Mahomes-Henne tandem. Love has talent and first-round pedigree, and Keenum won both of his starts last year, while Henne has started one game in the last five seasons.Split opinions on QBs entering big yearsThere are a few quarterbacks entering potential prove-it years for their careers who received very different reactions acro s our votersJameis Winston was rated as high as 13th and as low as 24th. Overall, he had the highest variance of any quarterback. Winston is coming off a torn ACL, but he went 5-2 as the Saints' starter last year, and his 102.8 pa ser rating was seventh among 38 quarterbacks who threw at least 150 pa ses. The Saints continued their win-now ways this offseason, and Winston is a ma sive piece of the puzzle.Tua Tagovailoa had the widest range between his best (16th) and worst (28th) rank. Health could certainly be a major part of that: After a major hip injury ended his college career, he has dealt with thumb, finger and rib injuries in the NFL. The Dolphins Orlando Magic T-Shirts invested heavily at the skill positions and along the offensive line have a new head coach in Mike McDaniel. It's a huge year for him.Like Tagovailoa, Jalen Hurts is a third-year quarterback who got a lot of help this offseason and received varying evaluations. His highest vote was 14th and his lowest was 21st. Hurts and Tagovailoa also both have backups whom our voters view highly: Teddy Bridgewater finished as the third-best backup, and Gardner Minshew was sixth.Other veterans in key years who had wide ranges included Matt Ryan (highest 14th, lowest 23rd) and Ca
