Possibly but again if they were playing with confidence then they would be more inclined to trust their own instincts.
Look at Drinkwater. We know he's a good player. He hasn't become a "shit" player. Regardless of where he's playing or how he's instructed to play the ball, he's a player who we know can pass the ball 1p yards accurately. Lately, they've been going all over the place.
Vardy would have at least hit the target with his chance against Burnley and yet he skewed it wide. This isn't him being "shit", I would argue he's probably over thinking it and snatching at chances.
I've said it before, the defence know that the strikers aren't scoring at the minute so they are under huge pressure not to concede. That leads to mistakes. The strikers know that the defenders are letting in goals so they need to try to score at least 2 a game so they are under massive pressure which leads to snatching. The midfielders have been changed around so much that they can't help either end. That's down to Ranieri though I'm not sure he had a huge amount of choice in the matter but it's also why I'd sooner stick with DD and NDIDI to get some consistency in there.
I can't and won't ever condone sacking Ranieri, not because of what he did last year or even because I think he'll keep us up; like most I'm sick and tired of the lack of so called "loyalty" shown by players and managers nowadays. Ranieri allegedly had the chance to leave us in the summer when his stock was the highest it could ever be. Same for Vardy, Mahrez etc (it's not about money, they'd easily have made the same at Arsenal etc). If they'd have left they'd have been called snakes, traitors whatever. Look at what happened to Kante's picture on the wall. I honestly feel that loyalty has to go both ways. It's very naive of me in the current system, I get that, but I'd sooner stick to what I believe than be dragged into the crowd.
