Quarterback Jaren Hall's learning curve accelerated Monday during the Vikings' first padded practice of training camp.
The fifth-round draft pick out of Brigham Young took a step up the depth chart, replacing veteran Nick Mullens as the backup behind Kirk Cousins. Mullens had an excused absence because of a family matter Monday.
Hall's longest completion required him to step up, evade pressure and throw between two defenders to receiver Blake Proehl. Proehl scooped the low throw off the turf. Hall said he can throw a better ball.
"It's just about finding space," Hall said Monday. "That's what I've learned in the NFL very quickly. There's not a lot of space. It's also timing. You have to be very accurate. Today was not great. A lot of missed throws by me. There's a lot I can work on."
The pressure increased Monday. Energetic rushers put on shoulder pads for the first time since January. While edge rusher Danielle Hunter didn't yet fully practice, Hall dodged Marcus Davenport, Harrison Phillips and other starters when the first-team defense faced the second-team offense in goal-line drills.
Cornerback Byron Murphy Jr. slapped away a Hall throw intended for receiver Thayer Thomas in the end zone. Hall felt the pressure, tucked and ran on another red-zone passing play.
"Just the speed is going to be faster," Hall said. "The D-line is moving a lot more. They don't have to hold up as much. So, you got to get used to playing from an awkward base at times, find space in the pocket. It's a lot smaller than it was in college."
Hall's first NFL padded practice shined a spotlight on some areas he would like to improve. He was intercepted by safety Harrison Smith during seven-on-seven passing drills.
