No quarterback has been sacked more than Chicago's Justin Fields this year. Can the Bears give their rookie QB better protection in Week 8 against the visiting San Francisco 49ers?

The Chicago Bears were routed 38-3 by Tampa Bay last week in a historic game that saw Bucs quarterback Tom Brady become the first player to ever record 600 career NFL passing touchdowns.  San Francisco also comes into Week 8 off a loss, after getting rinsed 30-18 at home against Indianapolis.

The 49ers are 4-point favourites to win on the NFL odds, with a total of 39.5.

NFL Point Spread and Betting Analysis

These teams haven’t met since December 2018, with Chicago winning 14-9 in San Francisco.  That low scoring affair has historically been the norm in these head-to-heads as the total has gone Under in three straight encounters.  It’s a trend that explains why over 60 per cent of Sports Interaction bettors are taking the Under in this one, despite the low 39.5 total.  A similar split is backing the 49ers to win.  Both teams has failed to score more than 18 points in each of their last two games.

San Francisco has now failed to win or cover in four straight games and they’re just 1-5 against the spread for the season.  The total has gone Under in five of the 49ers’ last seven road games, including one of three this year.

In the past the Bears have been fairly comfortable at home against San Francisco, taking five of the last seven meetings. Points have been hard to come by Chicago this year, though.  The Bears have failed to hit the Over in six straight games, only managing to go above the number in their season opener.  They’ve only scored more than 20 points once on their current six-game Under streak.  Chicago is 2-4 ATS for the season and 1-5 ATS in their last six against NFC opponents.

San Francisco 49ers

The return of starting quarterback Jimmy Garoppolo didn’t go the way San Francisco would have liked last week.  Garoppolo, who had missed the previous game with a calf injury, struggled to move the ball downfield.  He finished with 181 passing yards, one touchdown, two interceptions and lost a fumble.  The 49ers have struggled to keep the ball all year and that continued with their four turnovers as a team last week.  Discipline has also been a major issue, as they lead the NFL with 14 pass interference penalties.  There was at least one thing to build on for San Francisco, however.  They entered the game with a league-low two turnovers and doubled that number in the first half against Indy.

Chicago Bears

Justin Fields was terrorized by the Tampa Bay defence last week and sacked four times.  Chicago’s rookie quarterback has now been sacked a league-leading 22 times.  Ironically, the Khalil Mack-led pass rush is actually tied for first in the NFL with 21 sacks of their own.  Mack has been playing through a foot injury and is questionable for Week 8.  Fields, now 2-3 as a starter, finished last week with 184 passing yards, no touchdowns and three interceptions.  He also lost two fumbles.  The most immediate concerns for the Bears, however, is COVID problems.  Head coach Matt Nagy tested positive for COVID on Monday and he’ll only be allowed on the field this week if he can produce two negative tests before Sunday.  Linebacker Robert Quinn and tight end Jimmy Graham could also be out on Sunday after both players missed last week’s game because of COVID protocols.
