I think just like in the workplace, metrics tend to overrule intangibles simply because they allow some basis of comparison and are traceable, even when they're incomplete or garbage metrics. Each year teams seem to lose their minds based on combine performance. And I'll take an accurate QB over a guy who can throw the ball 90yds any day of the week, and yet more times than not it's the freak athlete who gets the call.
That said, I agree with you. Whether drafted or not, some team will look at Luke and see the intangibles, the leadership, the toughness and desire, the accuracy on slants and when given a clean pocket, and his ability to be a good locker room presence and will give him that chance. And knowing Luke, he'll make good on that and turn it into a long NFL career. Just needs to get with a well managed organization that knows what they're doing.
