After the initial team photos, when he was a freshman, came out, I mentioned that I was concerned by his countenance. His eyes just looked dead. I have studied and worked with another people who suffer from alcohol and chemical addiction to know that is a tell tale sign. When people recover, one of the first things people notice is a "light that comes on in their eyes" that they had never seen before. For a lot of alcoholics and addicts you can see that missing light all the way back to infancy. However, it seems some people lose the light along the way.
You can see that missing light in every picture of Tucker, at least from the time he became a Hawk - Even the one on the front of this story.
Hope the guy ends up getting help some day.
