The NFL prides itself on its parity. It doesn't take long for teams to engineer remarkable turnarounds so long as they hit on their draft picks and make smart upgrades in free agency. It doesn't much for teams to suffer staggering stumbles down the standings -- one or two bad drafts combined with natural regre sion in a few areas is more than Los Angeles Clippers Jersey enough to inflict significant damage. The 2019 season saw three of the eight division winners fail to repeat as division champions, with the in the NFC North, the in the NFC West, and the in the NFC East getting usurped by the , , and in their respective divisions. It's incredibly difficult to find sustained succe s in the NFL, which is why the ' run over the past two decades with Bill Belichick, who has guided the Patriots to 17 AFC East titles in a 20-season span, is a marvel. But the Patriots could be in trouble in 2020 in the aftermath of Tom Brady's decision to depart Boston for Tampa Bay. As the 2020 NFL season approaches and now that free agency and the draft have come and gone -- only a few notable players remain free agents -- we decided now would be an appropriate time to take a look at the eight reigning division champions and rank them by their level of vulnerability. The team ranked eighth is the team that is the least likely to get usurped by one of the other three teams in their division. The team ranked first is the team that is most likely to get usurped by one of the other three teams Montrezl Harrell Jersey in their division. Before we begin, it's worth noting that as much as these rankings are about the eight teams and their outlooks in 2020, it's as much about their level of competition within their divisions. As an example, you'll find the 49ers listed on the top half of the list even though they were the best team in the NFC a season ago and remain one of the league's most talented teams. The reason? They're stuck in the toughest division in all of football. All it'll take is mild regre sion combined with one of the three teams taking a step forward for the 49ers to surrender their crown. Ranking the 49ers as high as I did is not me saying the 49ers are the fourth-worst team on this list. It's me saying their road to the NFC West crown is far more treacherous than the Eagles' road to the NFC East crown because the Eagles only have to fend off one team as opposed to three. On that note, we begin in Kansas City with the defending AFC West and champions. 8. (AFC West) Since Andy Reid arrived in Kansas City, the Chiefs have won four division titles in seven seasons. All four have come in the past four seasons Louis Williams Jersey . Two came with at quarterback. The other two came with , inarguably the best player in football right now. At this point, it's impo sible to take anyone other than the Chiefs to win the AFC West. While the and both made substantial improvements this offseason, both teams are a long ways off from competing with the Chiefs, who by the way, are 11-1 against the AFC West over the past two seasons. The Raiders still haven't solved their long-term problem at quarterback, even if gives them a decent insurance plan in the likely event struggles, once again, to make the leap in 2020. The Broncos are still a huge unknown with at quarterback after he flashed promised during his rookie season, but ultimately hasn't shown enough in only five starts to be deemed a franchise-caliber quarterback. As for the , their defense should be improved after they added in free agency, but they'll be starting either , a fringe NFL starter, or , a rookie who exhibited clear flaws during his college career, at quarterback. Neither should be expected to keep pace with Mahomes. In the end, it comes down to the Chiefs having Mahomes and Reid. It makes placing the Chiefs on this list rather easy. Nobody should expect Kansas City to regre s in 2019. 7. (AFC North) The Ravens were the best team in football a year ago during the regular season, winning 12 straight games after starting 2-2, with capturing MVP honors. They weren't at all lucky to win as many games as they did with an offense that and . They outscored their opposition by 249 points over the course of the season. Don't let their disappointing performance in the playoffs fool you: The Ravens had an incredible 2019 season, and and in the first round of the draft, they're primed to sustain their succe s in 2020. Even if they do take a step back -- it Jerome Robinson Jersey 's extremely difficult to win 14 games two years in a row -- they can still win the division with 10 or 11 wins. While the should be improved without and under center, they're counting on -- at the age of 38, , and -- to elevate them above the Ravens. The are still the Browns, talented, but flawed -- until they demonstrate they're a playoff-caliber team, it's best to avoid picking them to make the playoffs (says the guy who picked them to do exactly that a year ago). As for the , while their long-term future is bright with , they were able to pick Burrow first overall for a reason: They're not any good. It comes down to how much you think the Ravens will regre s after a 14-2 season and how many wins Big Ben is worth. While I think the Ravens will win closer to 10 games than 16 games, I also don't think the Steelers will improve as much as we think just because of Big Ben. Remember, defensive succe s tends to fluctuate on a year-to-year basis, and the Steelers rode their defense to eight wins. That same defense racked up a league-high 38 takeaways, which also tends to fluctuate on a year-to-year basis. What I'm trying to say is that the Steelers' defense could very well regre s in Avery Bradley Jersey 2020, which means it'll be up to a 38-year-old quarterback coming off major surgery to lead the Steelers past a team that went 14-2 a year ago. I'll take the Ravens, a suming Jackson stays healthy, of course. 6. (NFC South) Tom Brady's arrival in Tampa Bay has certainly made the NFC South more competitive than it was a year ago, when the Saints won 13 games and second place belonged to the 7-9 and 7-9 , but the NFC South is still very much the Saints' division. They're bringing back most of their important contributors, most notably . Their biggest lo s was , their backup quarterback who won all five of his starts filling in for Brees a year ago, but they managed to replace him with , giving them the. Over the past three seasons, with so many of the components that compose the Saints' current core, Blake Griffin Jersey the Saints have gone 37-11. A suming the Saints will win anywhere between 11-13 games, as they've done over the past three years, the question then becomes if you think Tom Brady and are worth 4-6 wins. For as good as that duo was together in New England, I'm skeptical. While Brady, who will be 43 when the season begins, didn't have much help a year ago, he graded out as a fairly average quarterback by the advanced metrics ( ). Meanwhile, Gronk clearly wasn't operating anywhere close to his peak the last time we saw him in 2018. I don't want this to come acro s as an ov
