​What a win for the San Francisco 49ers in Week 5. They beat the Seattle Seahawks 32-29 in a wild, back-and-forth defensive struggle. A defensive struggle with 61 points scored seems impossible, but that’s what we witnessed Sunday at Lumen Field. A lot happened in Sunday’s game. Here’s what we learned:Mike Evans is awesomeThere’s no better stat that illustrates Evans’s impact on Sunday’s game than this one: On San Francisco’s go-ahead touchdown drive in the fourth quarter they were credited with 74 net yards. Evans on that drive had 75 receiving yards. Every time the 49ers needed a big play, Brock Purdy looked for No. 5 and Evans came through every time. He caught 7-of-10 targets for 113 yards and a touchdown. He also came through with a two-point conversion grab that put San Francisco up three in the fourth quarter. Huge win for NFC West standingsIt’s too early to look at division standings with any kind of intensity, but the victory was a big one early in the season for San Francisco from that standpoint. With the Los Angeles Rams set to host the Buffalo Bills on Monday Night Football, here’s what the standings look like after Sunday’s action:49ers (5-0)Seahawks (3-2)Rams (2-2)Cardinals (1-4)San Francisco has at least a two-game cushion on all three divisional opponents, and they hold the head-to-head tiebreaker going into their second matchups with each team. They’re in a good spot with almost a third of the season down. Run defense showed upMore on some specific players in a moment, but the 49ers run defense was outstanding in Seattle. The Seahawks managed just 89 rushing yards on 26 attempts Sunday, with just 68 of those yards coming from running backs on 24 carries. Seattle also managed just one explosive run and that came on a throw behind the line of scrimmage to WR Jaxon Smith-Njigba. It was an excellent showing from all three levels of the 49ers defense to get stops in an area they’ve struggled this season. Seattle spent a lot of time in second or third and long thanks in large part to the work of the run defense. Sack partyWe promise there’s more coming on individual players in a second. The run defense that left Seattle off schedule on offense also allowed San Francisco’s pass rush to get home for five sacks. They impacted even more plays than that with eight players getting credited with a quarterback hit. The last time San Francisco had five sacks in a game was Dec. 8, 2024 in a win over the Chicago Bears. They’re up to 11 sacks this season − a number they didn’t reach until Week 13 last year.Young defenders shineOkay, some specifics. There were a handful of awesome defensive performances from veterans Sunday. Fred Warner was his Hall of Fame self and Osa Odighizuwa was dominant, but a handful of players still on rookie contracts came up with big games. Here are their stat lines:DT Gracen Halton: 3 tackles, 1.0 sacks, 2 tackles for loss, forced fumble, fumble recovery, touchdownDL Keion White: 3 tackles, 1.0 sacks, 2 tackles for lo
