I had an excellent discussion about this a while ago, and anyone if this is BS call it out or if you heard similar let me know, but it really had little to do with Lingards wiggle.
Lingard was spoiled by his HS so that messed up his mindset.
Secondarily, they ran absolutely basic offense, essentially running nothing but 3-4 plays so he never developed vision or the discipline to learn plays or the position.
So when you are spoiled and don’t know the position your going to be a bad student since you probably think you know it all but know almost Jack ****.
