3 key matchups: Vikings at Falcons

Vikings WR Stefon Diggs vs. Falcons CB Jalen Collins: Diggs has 36 catches for 573 yards and two touchdowns. Collins is coming off a shaky showing against the Colts. Diggs, despite being active for only seven games, has the second-most receiving yards among all rookies with 573 yards, trailing only Oakland's Amari Cooper, who has 736 through 10 games. Diggs, a fifth-round pick out of Maryland, also leads all qualifying rookies with a 15.9 average per catch. Collins, a second-round pick out of LSU, has played well in spurts, but had a critical holding penalty against the Colts.

Vikings NT Linval Joseph vs. Falcons C Mike Person: Joseph is a load inside at 6-feet-4, 329 pounds. Person will receive help from left guard Chris Chester. Joseph has 51 tackles, the most in the NFL among defensive linemen, and the Falcons will try to make him move from side to side with their outside-zone rushing scheme. Person will have to anchor the front in pass protection.

Vikings TE Kyle Rudolph vs. Falcons SS William Moore: Rudolph has 29 catches for 288 yards and a team-leading four touchdown receptions. He set a career-high with 106 receiving yards on six catches against the Packers, including a career-long 47-yard touchdown catch. The Falcons struggled against tight ends in losses to New Orleans and San Francisco during their 1-4 slide.
