Top 2021 Week 9 NFL prop picks

One Week 9 NFL prop bet PropStarz is definitely backing: Vikings receiver Justin Jefferson to go over 73.5 receiving yards. The second-year pro hadn't failed to eclipse that number in four weeks until the Vikings' offense fizzled against the Cowboys last Sunday. Jefferson was targeted just four times, catching two balls for 21 yards, as the Vikings converted just one of 13 on third down in a 20-16 loss.

However, Jefferson has been targeted at least seven times in every other game this season, and the 2020 first-round pick is primed for a rebound. The Ravens' defense is fourth in the NFL against the run, but ranks last in passing yards allowed (296 per game). The Vikings average more than 39 pass attempts per game, so it should be a shootout on Sunday. "I think this prop should have been set closer to 79.5, and I'll gladly take the discount," PropStarz told SportsLine.
