TODAY’S VIKINGS SCHEDULE

After their 10:30 a.m. morning walkthrough, the Vikings will hold their second night practice of Camp Zimmer at 7:30 p.m. It is not a scrimmage, but there should be live tackling in some drills.

SOMETHING TO THINK ABOUT

Head coach Mike Zimmer has said on several occasions that tackling ability will be a major determining factor in the battle at safety. And understandably so, because the Vikings had no safeties who ranked in the top 40 in the league in Pro Football Focus' tackling efficiency rating in 2013. Harrison Smith was the team’s most reliable tackler, missing one tackle for every 9.1 attempts and eight total tackles overall. Jamarca Sanford and Andrew Sendejo fared a little worse.
