Every so often on Wednesday mornings, the "two little angels" — or perhaps they're devils, Mike Zimmer says — show up in the coach's office, armed with GPS data about how hard players have worked in the past few days and which ones might be due for a break.
This week, head strength and conditioning coach Josh Hingst and head athletic trainer Eric Sugarman were united in their message: After a physical game in San Francisco, where the 49ers ran the ball for 208 yards and kept the Vikings' defense on the field for 37:07, players needed to rest.
So for the second time in 21 days, the Vikings turned their Wednesday practice — ordinarily their most important of the week — into a walk-through, betting on extra recovery over extra repetitions.
"They actually talked me into it today. I had them both in my office this morning," Zimmer said Wednesday. "They were both saying the same thing today, and usually I'm the one saying the opposite most of the time. I tell them, 'We better win, or it's...'"
Zimmer trailed off, but it's not hard to imagine what he might have said in response. The coach was raised in an era of longer and more grueling practices, and still believes on-field work is where players learn best. On Wednesday, he still sounded cautious about granting the walk-through, given the practice snaps it would cost young players.
"It's hard for me, anyway, but we do have some older players that we have to take care of," Zimmer said. "There's a fine line with some of the young guys that ... don't get as good [of] work as they would, but I think it's important that we continue to try to stay fresh. Like I told them this morning, they've been emptying their buckets for me and for them each and every week, so I'm trying to take care of them so they can do that again on Sunday."
In addition to the walk-throughs after the Ravens and 49ers games, the Vikings have given Wednesday rest days to Harrison Smith three times, Everson Griffen twice and Patrick Peterson, Rashod Hill and Adam Thielen once each.
While they'll head to Detroit without the services of running back Dalvin Cook (out with a dislocated shoulder), left tackle Christian Darrisaw (ankle injury) and safety Camryn Bynum (ankle injury), injuries haven't taken their key players off the field all that much this season. The Vikings have suffered the ninth-lowest injury impact in the NFL this season, as measured by the Lost AV metric from Man Games Lost, which is derived from Pro Football Reference's Approximate Value statistic to quantify the importance of injured players.
