The NCAA is the governing body for collegiate sports, of which there are three divisions. Schools that belong to Division 1 typically have the highest level of competition, while Division 3 is the lowest.

The Saints are a professional American Football team. A lineman is a defensive player on a football team. Being selected as an "All-Pro" means the player was voted as one of the best players in his position in the entire league (and I guess by extension, the world) during that season.

This person was an extreme outlier in the sea of otherwise average students/graduates at this school.
