Whether you like Dak or not, his hourglass could be half empty already. He's been at it too long for his draft status to matter. He's on his second contract. He's not the new guy and he's not replacing anyone at this point. He's surrounded with some talent. He should be healthy. All careers are eventually a culmination of everything that was done.
His story isn't complete. But he has missed opportunities to write a better story that what his first few chapters now hold. An NFL career doesn't give you very many chances. I hope he gets it done here, but he hasn't yet.
