Let's not waste time with a long preamble. It's Championship Sunday in the NFL and this first game has kicked off. In the NFC Championship, the No. 1 seed and NFC East champion will play host to the No. 2 seed and NFC West champion .These were the two best teams in the conference for the significant majority of the season, and they will duke it out for the right to represent the NFC in the . Before we break down the matchup, here's a look at how you can watch the game.Date:Sunday, Jan. 29 |Time:3 p.m. ETLocation:Lincoln Financial Field (Philadelphia)TV:Fox|Stream:fuboTV ( ) Odds: Eagles -2.5, O/U 46 (Courtesy of Caesars Sportsbook) Featured Game | Philadelphia Eagles vs. San Francisco 49ers Moneyline Spread Total PHI SF SF QB #13 CMP%67.1YDs1374TD13INT4YD/Att8.08 Let's start by talking about , because how he handles the Philadelphia pa s rush might be the tipping point of this game. Prior to last week's game against the , Purdy had dropped back to pa s 177 times since taking over for back in Week 13. He'd completed 110-of-161 pa ses (68.3%) for 1,308 yards (8.12 per attempt), 13 touchdowns and just three interceptions. He was sacked 11 times, and faced pre sure at an almost exactly Kendall Graveman Jersey league-average rate (32.8% vs. 32.6%). The Dallas rush was able to get after Purdy a bit more regularly last week (48.5% pre sure rate, per Tru Media), and though Purdy was sacked only twice and did not get picked off (though he did have one potential interception dropped), his efficiency took a hit (7.38 yards per attempt).During the regular season, the Cowboys were the league's best team at getting pre sure (43.3% of opponent dropbacks), but the Eagles were right behind them in second place (38.4%). And the Eagles were quite a bit better at converting pre sure into sacks: 11.2% of Philly's pre sures resulted in quarterback takedowns (first in the ), compared with 8.9% of Dallas' pre sures (second). That difference could be incredibly meaningful in this matchup.The Eagles can throw even more bodies at their pa s rush than the Cowboys can. Jonathan Gannon will rotate through , , , and on the edge, while bringing (mostly) and up the middle. San Francisco has an elite left tackle in on the left side of Walt Weiss Jersey the line, but can be vulnerable on the right, and guards and are better at run-blocking than they are in pa s protection. SF TE #85 TAR86REC60REC YDs765REC TD11FL1 Of course, Kyle Shanahan is perhaps the league's premier offensive schemer at the moment, and he will undoubtedly create advantages for Purdy. Shanahan has a lot of tools at his disposal to create wide throwing lanes: Just 9.4% of Purdy's pa ses were thrown into a tight window this season, according to NFL.com's Next Gen Stats, good for the second-lowest rate in the NFL. Those wide lanes often give the likes of , , and a ton of room to run with the ball, which is why Purdy ranks third in the NFL behind only Garoppolo and in yards after catch per completion (6.45).Shanahan figures to move Samuel and Aiyuk around the formation so as to not consistently subject them to either or on the outside, but the expected return of Eagles slot corner mitigates that strategy a bit. Philadelphia ranked 27th in succe s rate against throws to the slot when Maddox was off the field this season, per Tru Media, and first when Maddox was on the field. Having him back in the fold should make a big difference.We know the San Francisco offense is designed to attack the middle of the field, and it's likely that Shanahan, Purdy and Co. will try to take advantage of Philadelphia's linebackers. (Kittle should be heavily featured here.) Much of that middle-of-the-field pa sing game is based around the play-action attack, though, and Philly was first in EPA per opponent dropback against play-action pa Dave Henderson Jersey ses this season. Opponents completed just 59.7% of their pa ses at an average of 6.56 yards per attempt, while throwing six touchdowns against five interceptions. The 49ers' play-action pa sing attack is a lot different than a standard one leaguewide, but there is reason to believe Philly is better equipped than most opponents to handle it. SF RB #23 Att244Yds1139TD8FL0 Because of all these factors, it's likely that the Niners will try to fight this battle in the run game. Philadelphia was far better against the pa s (first in Football Outsiders' DVOA) than the run (21st) this season, though the Eagles have been better in that department when able to use at least one of and/or . The San Francisco rushing attack tests teams with both diversity and misdirection. It' Terry Steinbach Jersey s no longer just outside zone after outside zone after outside zone. The 49ers will run all kinds of schemes now, and give the ball to a bunch of different players. They'll force opponents to declare their intentions based on where Samuel or McCaffrey or Aiyuk or line up, and then use those intentions against them.Philadelphia's defense doesn't have quite as much speed as the Dallas unit against which San Francisco went against last week (there are very few players faster than , after all), so the Eagles might be a bit more vulnerable to the perimeter runs they didn't see much succe s in the divisional round. The Niners will use any of McCaffrey, Samuel or (if he plays) on those runs, and they can each hurt the defense in different ways. PHI QB #1 CMP%66.5YDs3701TD22INT6YD/Att8.05 The best thing about Philadelphia's offense this season is that it has shown a remarkable ability to shapeshift in order to attack an opponent's specific weakne ses. Bad against the run? The Eagles will pound the rock all day, like they did in rushing for more than 250 yards in two different games against the Giants, and a preposterous 363 yards against the . Weak against the pa s? They'll light you up through the air, like when they had just 19 running back rushing attempts against 39 pa ses against the , and he torched them for 380 yards and three scores. The 49ers defense is great at just about everything. The Niners finished the regular season second in rush defense DVOA, and fifth against the pa s. They were first in EPA per dropback AND first in EPA per rush attempt. They generated pre sure and sacks at an above-average rate, and they ranked third in the league in yards allowed before contact per rush and first in yards after contact. They rarely allowed explosive pa ses or runs, and they were arguably Matt Joyce Jersey the best tackling team in the NFL. They're incredibly well-coached, and they have a few absolute freaks who can wreck any opponent's game plan in , , and . PHI WR #11 TAR145REC88REC YDs1496REC TD11FL2 So, where are the Eagles to attack? To me, it's deep down the field. The 49ers were first in DVOA against short pa ses, but just 24th against deep pa ses.
