49ers' Kyle Shanahan on Steve Wilks' blitz ahead of halftime vs. Vikings: 'He knows he messed up'

Speaking to reporters after Monday night's loss to the Minnesota Vikings, San Francisco 49ers head Kyle Shanahan was asked about one specific play—the zero blitz just moments before halftime. While the coach likes the call in certain scenarios, he firmly believes that this particular instance was ill-timed, and the result was disastrous.

The pass from Vikings quarterback Kirk Cousins found the hands of wide receiver Jordan Addison, resulting in a seemingly effortless 60-yard touchdown.

"He knows he messed up on that call," Shanahan told reporters before Wednesday's practice. "I have no problem with zero blitzes, especially when people need a lot of yards. If you need to get 20 yards to kick a field goal, I have no problem with a zero blitz, but I do [have a problem] when there's 16 seconds left, and that's where he lost track.

"There was no necessary need for that, just because of the time. I have no problem with that play call, but when it's that time, you can't do that. That's not an option."

Instead of heading into halftime down 10-7, the 49ers found themselves training 16-7 after two quarters of action, ultimately losing the game 22-17.

Since Monday night's loss, Wilks has come under significant scrutiny, stemming from the questionable play call and the underperformance of the talented defensive line, which has failed to reach opposing quarterbacks consistently.
