It's always dangerous to read body language, especially while doing it by way of national television. Still, something looks off with DeSean Jackson on the sideline during Thursday Night Football. He's distant and just doesn't seem to be interacting with his teammates.
Nothing illustrates this better than his second quarter encounter with quarterback Vince Young. Jackson, sitting on the bench and staring straight ahead, is approached by Young, but never acknowledges him. As Young appears to be talking to the star receiver, Jackson continues to star straight ahead, all while keeping a stone face.
It was just odd all-around. Here's video of the encounter.
We can pick this apart and try to analyze whatever Jackson is thinking, but judge it for yourself. It's just a weird situation, perhaps compounded by Jackson's one catch for just five yards thus far.
