In the NFL, nothing is ever completely certain, with the lone exception of the being in position to win another Super Bowl. The 2019 regular season proved it again, with more than a handful of outcomes that made us scratch our heads and wonder, how'd that happen? These games were outliers which didn't seem to fit in with what we saw the rest of the season, although it some cases we didn't realize it at the time. They not only added to the fun of the NFL's centennial season, but also reinforced the notion that anything can happen in the NFL on any given Sunday.So, before we move on to the final weekend Christian Okoye Jersey of the regular season, we thought it would be fun to take a look at six of the biggest outliers of 2019 so far.1. Browns whip Ravens in BaltimoreNot many people were overly surprised when the Browns went to M&T Bank Stadium in Week 4 and ran through, over and around the Ravens to even their record at 2-2 through four weeks. Cleveland, not Baltimore, was the popular pick to win the AFC North, and the Ravens were coming off a Week 3 lo s to the that saw them allow 33 points to and Kansas City's top flight offensive attack. Three months later, however, it's hard to fathom the Ravens allowing 40 points to anyone, much le s a Browns team that is ranked 22nd in the league in scoring. So, how did the Browns pull this off? Cleveland's defense forced three turnovers that included two interceptions of MVP front-runner , who threw just six interceptions during the entire season. The Browns also received three rushing touchdowns from , including an 88-yard scoring jaunt that pushed Cleveland's lead to 30-18 with just under 10 minutes remaining. The Ravens' defense had also not yet acquired cornerback , who would quickly helped morph Baltimore's defense from a slightly above average group to one of the NFL's premier defensive units. Turning Point: beating the with an 88-yard run by Nick Chubb. Dov Kleiman (@NFL_DovKleiman) The Browns' 40-25 win stands as Cleveland's most impre sive victory in a season that had far fewer wins than many expected. The Ravens, conversely, haven't lost since that game and have already locked up the No. 1 seed heading into the AFC playoffs.2. Jets shock CowboysA week before "seeing ghosts" against the Patriots, Jets quarterback had the Cowboys seeing stars during New York's stunning Week 5 win over the Cowboys. Darnold, who had mi sed the Jets' previous three games with James Winchester Jersey mono, riddled the Cowboys' defense to the tune of 338 yards and two touchdowns in a 24-22 win that gave the Jets their first win of the season after an 0-4 start. The Cowboys, who sprinted out to a 3-0 start, fell to 3-3 while offering a glimpse into what their season would ultimately become. While started the game with a one-yard touchdown run, the Jets' offensive stars on this day were Darnold and receivers Robbie Anderson and . Anderson led both teams with 125 yards that Justin Reid Jersey included a 92-yard reception that gave the Jets a 14-3 second quarter lead. Crowder caught six pa ses for 98 yards that included a 30-yard catch that set up New York's final points: a 38-yard field goal by with 3:27 left. J-E-T-S, JETS Jets Jets Jets!Darnold hits Robbie Anderson for the longest play from scrimmage in the NFL so far this year! Cowboys -7.5 bettors are puckered right now. MyBookie Sportsbook (@betmybookie) The Cowboys, after falling behind 21-3, fought back to make it a two-point game after quarterback scored on a four-yard run with 47 seconds remaining. Prescott's game-tying pa s attempt on the two-point try fell flat, however, as the Jets then recovered Dallas' onside kick to preserve the win.While the Jets would ultimately fall to 1-7 before righting the ship during the second half of the season (they are now 6-9 entering Sunday's season-finale against the ), the Cowboys are a disappointing 7-8 and need a win over Washington and an lo s to the just to make the playoffs. 3. Colts corral Patrick Mahomes, Chiefs offenseThe Chiefs, led by reigning MVP Patrick Mahomes, have scored at least 23 points in 14 of their 15 games this season. They scored at least 26 points in each of their 18 games during the 2018 season, including the playoffs. The only game that Clyde Edwards-Helaire Jersey Mahomes has not led the Chiefs to at least 23 points came in Kansas City's 19-13 lo s to the visiting Colts in Week 5.In front of a "Sunday Night Football" audience, Indianapolis' defense, a unit that is currently 15th in the NFL in points allowed, held Mahomes and the rest of the Chiefs' offense to 18 first downs and 4-12 efficiency on third down. Safety recorded an interception of Mahomes, while the Chiefs also didn't help themselves by committing 11 penalties for 124 yards. Kansas City's offensive ineptitude could also be attributed to the health of Mahomes, who re-aggravated an ankle injury during the first half of the game that would eventually sideline him for two games. Revenge of the Horseshoe!Colts shutdown the Chiefs 19-13, avenging last seasons playoff defeat. Justin Houston made KC pay.Bri sett: 18-29, 151 YDS, 1 INT NFL Guy95 (@NFLFBGAMETIME) The Colts' ability to run was a major reason why Indianapolis pulled off one of the bigger upsets of the season. While Kansas City gained just 36 yards on the ground, Indianapolis rushed for 180 yards and a score on 45 carries. , arguably the Colts' best offensive player this season, led the way by rushing for 132 yards on 29 carries. And while he wasn't prolific, quarterback was efficient, going 18-of-29 through the air while scoring the Colts' only touchdown on a one-yard touchdown. While his kicking was erratic all season, enjoyed arguably his finest moment of 2019 against the Chiefs, scoring the Colts' final 12 points while helping Indianapolis head into their bye week with a 3-2 record.The Chiefs, who did not have receiver for the early portions of the season, started slow before winning five straight heading into their season-finale finale against the . The Colts, who improved to 5-2 before mounting injuries led to six lo ses over a seven-week span, are hoping to end the season with a .500 record by defeating the on Sunday.4. Bengals nearly upset Seahawks in Week 1No one thought too terribly much -- at the time -- of Cincinnati nearly pulling off an upset in Seattle against the Seahawks back in Week 1. Seattle was coming off a 10-win season, but not many people expected them to be in the position that they are in now, as the Seahawks are still vying for a po sible playoff bye as well as an NFC West division title. And while the Bengals weren't expected to be good during Zac Taylor's first season in Cincinnati, no one was predicting the Bengals to win just one game and already lock up the draft's No. 1 pick entering their Week 17 matchup against Cleveland. But now, looking back on it, Rashad Fenton Jersey seeing the score "Seattle 21, Cincinnati 20" looks downright bizarre. How in the world di
