Undrafted Vikings Rookie Zach Line: 61 Yards, 5 StitchesPreseason games might not provide much in terms of seeing the starters, but they're a crucial audition for the guys trying to make a roster spot.

He only touched the ball one time, but Line made it last as long as he could: 61 yards, all the way to the end zone. “[Wide receiver Stephen Burton] made a nice block for me, made it easy for me to get down the field. Seriously, he’s just a, like a chariot riding down the sidelines,” Line said.
