Vikings going back to Jaren Hall; what's it mean for WRs?

The Vikings have announced that QB Jaren Hall will start over Nick Mullens this Sunday night against the Packers. That comes after Mullens tossed 4 INTs in a 6-point Week 16 loss to Detroit. HC Kevin O'Connell originally had Hall as the backup to Kirk Cousins and started the fifth-round rookie in the first game after Cousins' season-ending injury. But O'Connell then stuck with QB Joshua Dobbs even after Hall returned from his concussion, and then rolled out Mullens after Dobbs' 4-INT turn against Chicago. This week's move says O'Connell believes Hall to be a better option than Mullens. But the rookie clearly remains unproven. He has thrown just 10 regular-season passes. The preseason found him completing just 54.2% of his passes at 5.5 yards per attempt. Hall does bring above-average speed for the position and topped 300 rushing yards in each of his final two seasons at BYU. But starting a QB in what would be his first full NFL game would obviously be very risky. The bigger question is what the switch does to WR outlooks. We'd still start Justin Jefferson comfortably. K.J. Osborn, meanwhile, is tougher to like inside WR3 territory. (He already landed as a WR4 in our Week 17 rankings.)

Vikings QB Jaren Hall went to the locker room in the first quarter of Sunday's game vs. the Falcons, presumably to get checked for a concussion. He'll be replaced by QB Josh Dobbs, who was just acquired earlier this week. We'll update Hall's status when we know more.

Update: Hall has been ruled out with a concussion.

Vikings HC Kevin O'Connell said Tuesday that QB Jaren Hall will start this weekend's game vs. the Falcons. QB Josh Dobbs will need at least a week to get up to speed in the offense. Hall replaced QB Kirk Cousins last week, completing three of four passes for 23 yards on 11 snaps. The fifth-round rookie started for BYU the past two years, completing 65% of his passes at 8.6 yards per attempt with 51 TDs vs. 11 INTs. Hall also ran for 657 yards and six TDs across those two seasons and then clocked a 4.64-second 40 time at his Pro Day. There's some rushing potential here, but Hall is just a desperation QB2 play this week. He adds obvious risk to Minnesota's pass catchers.
