I can't speak to his ability to catch the ball but Curtis Brown was a pretty good running back. I believe one year he led the Bills in rushing and was voted team MVP by his teammates.
I remember much about Tom Ruud except the position he played. He had a pretty forgettable career.
I know that he and second rounder Bob Nelson were dubbed "The Minnesota Twins" because while both played collegiately at Nebraska, they both played high school in Minnesota. And as was pointed out upthread, Nelson had a good career as a middle linebacker which makes me think Ruud played the outside.
But for some reason I thought Ruud was a MLB too. His son Barrett has played the middle/inside as an NFL LB.
I always thought of Leon-hard as more of a Kelso-type player because of his lack of size.
And decent ball skills.
