49ers vs Cardinals Odds & Picks Week 18: In Dobbs We Trust In Season Finale

The Arizona Cardinals are 4.5-point favorites while hosting the San Francisco 49ers in Week 18 action Sunday. Oddsmakers set the total at 42.5 for this game which has no playoff implications.

This is a rematch of these teams' Week 5 game when Arizona stunned San Francisco 24-23 in Week 5. Recently, both teams have been playing poorly as the 49ers are riding a three game losing streak and the Cardinals have lost five of their last six games.

49ers vs Cardinals Week 18 Picks

49ers +4.5 (-115)

Both teams looked strong at times in their losses last week, but the 49ers showed more fight in their loss to the Lions.

San Francisco will be looking for revenge after being embarrassed by Arizona earlier this season in a game they should have won. The 49ers were the better team on third down that day, had more first downs, more time of possession, but somehow found a way to lose.

Brock Purdy is likely to miss this game for the 49ers, but as miserable as he's been lately (4 INTs in his last three games) maybe getting an inspired Josh Dobbs into the lineup can give San Francisco a much needed spark. This will be a revenge spot for Dobbs vs his former team.

The 49ers achilles heal this season has been their redzone defense which ranks 28th in the NFL. Luckily for San Francisco, Arizona has been mediocre at punching it into the endzone from inside the 20 and ranks 22nd in redzone offense.

San Francisco wide receiver Jauan Jennings is 77 yards shy of his first 1000 yard season and he should have a big day against this Cardinals secondary.

Jauan Jennings O77.5 rec. yards (-130)

Yes, this number is a bit inflated from where it normally is, but it's for good reason. Jennings is 77 yards shy of the 1,000 yard mark and coaches have acknowledge in the media how important it is for them to see Jennings hit that mark. Jennings is a locker room favorite, known for his fierce blocking, and his teammates all want him to hit the milestone. 

Jennings has his former college teammate (Josh Dobbs) throwing him the ball which can only help matters.

49ers vs Cardinals Week 18 News

Brock Purdy sustained an elbow injury and Josh Dobbs was named the starter. Both WR Deebo Samuel and CB Deommodore Lenoir didn't practice on Wednesday or Thursday so there's now a decent chance neither of them play.
