And with that being the case, I expect it to come down to the wire.<\/p>\n\n\n\n<p>Backing either team to cover a touchdown would work. But San Francisco doesn&#8217;t get blown out when Purdy is under centre, so I&#8217;m very confident the Niners can cover this number, if not win outright.  <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The Niners are 7-1 when Purdy has played this year, with the lone loss being by five points to the 12-4 Jaguars.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In those games, they averaged 31.5 PPG.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Purdy has covered this number in all six starts vs. Seattle, winning five of those games outright.<\/li>\n<\/ul>\n\n\n\n<p class=\"acq_only\"><strong>-&gt; <a href=\"https:\/\/online.northstarbets.ca\/page?key=ej0xMzUyNDU3MiZsPTEzNjY1NzMyJnA9MzExMjU%3D\">Don&#8217;t miss out \u2014 click here to bet on Seahawks vs. 49ers<\/a>!<\/strong><\/p>\n\n\n\n<p>This pick isn&#8217;t disrespecting the Seahawks in any way. They&#8217;re a great team. But I have more faith in the home side coming through in a divisional showdown.  <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Saturday night football SGP picks<\/h3>\n\n\n\n<p><strong>Purdy 2+ passing TDs (-137):<\/strong> Remember when there was chatter that Mac Jones could do Purdy&#8217;s job as well as him? <\/p>\n\n\n\n<p>Hopefully, that stays in the past.<\/p>\n\n\n\n<p>Purdy has been spinning it lately, throwing for 16 touchdowns with a 111.5 passer rating during the Niners&#8217; six-game winning streak.<\/p>\n\n\n\n<p class=\"acq_only\"><strong>-&gt; <a href=\"https:\/\/online.northstarbets.ca\/page?key=ej0xMzUyNDU3MiZsPTEzNjY1NzMyJnA9MzExMjU%3D\">Check out NorthStar Bets&#8217; SNF prop markets<\/a>!<\/strong><\/p>\n\n\n\n<p>He&#8217;s thrown three-plus TDs in three straight weeks, and is 6-2 against this line on the season. That includes a two-touchdown performance against the Seahawks in Week 1.<\/p>\n\n\n\n<p>Seattle&#8217;s pass defence is elite, but so is Purdy. I trust him to perform with the top seed on the line. <\/p>\n\n\n\n<p><strong>Kittle anytime TD (+155):<\/strong> This is a logical addition after backing Purdy to throw multiple TDs.<\/p>\n\n\n\n<p>Kittle is returning to action after missing last week&#8217;s game, and that should make a big difference in San Francisco&#8217;s red zone offence.<\/p>\n\n\n\n<p>The star tight end was on fire before getting hurt, logging 15 catches for 203 yards and two TDs in Weeks 15 and 16.<\/p>\n\n\n\n<p>He scored against the Seahawks earlier this year and has caught 28 TDs in 44 regular-season games with Purdy in his career, per Stat Muse. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Top Seahawks prop bet<\/h3>\n\n\n\n<p><strong>Barner 30+ receiving yards (-200):<\/strong> Stopping Jaxon Smith-Njigba should be priority No. 1, 2 and 3 for the 49ers&#8217; defence. <\/p>\n\n\n\n<p>That&#8217;s easier said than done, and I still think the wideout should eat. But Barner, in my opinion, will be the next man up when the Niners are double and triple-covering JSN.<\/p>\n\n\n\n<p>Barner accounts for 15.1% of his team&#8217;s targets, which ranks in the 81st percentile among all tight ends, per RotoWire.<\/p>\n\n\n\n<p>And opposing QBs have a 98.2 passer rating when targeting San Fran&#8217;s linebackers (who typically cover tight ends). That ranks in the sixth percentile.<\/p>\n\n\n\n<p>Barner has reached this milestone in four of his last seven games, landing on exactly 27 yards twice.<\/p>\n\n\n\n<p><em>Seahawks vs. 49ers<\/em> <em>predictions made at 12 p.m. ET on Jan. 3, 2026.<\/em><\/p>\n\n\n\n<p class=\"acq_only\"><strong>-&gt; <a href=\"https:\/\/online.northstarbets.ca\/page?key=ej0xMzUyNDU3MiZsPTEzNjY1NzMyJnA9MzExMjU%3D\">Sign up to NorthStar Bets today<\/a>!<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The NFC&#8217;s top seed is up for grabs on Saturday night when the San Francisco 49ers (12-4) host the Seattle Seahawks (13-3) in Week 18.
