While I absolutely empathize with Visger's plight, fact of the matter is records show he only played sparingly in 3 NFL games. So while he's talking about getting financial help from the NFL, it's very likely most of his damage was done at the high school or college level. Why not chase them for money?
I guess Deion Sanders was correct about this topic, a lot of the lawsuits against the NFL are only about money. Visger probably sustained most of his damage prior to reaching the pros, but since the NFL generates billions, they are the targets of the lawsuits, not the high schools and colleges?
If anything, this story about Visger shows how dangerous high school and college football can be. And, according to the article, he played high school and college ball in the 1970's. Imagine how bad things are now, with so many "super athletes" on steroids and offensive lineman (sumo's) weighing 360 pounds, instead of weighing 260 (or less), as they did in Visger's era.
