Broncos S David Bruton made a "big jump" in spring practices. "Every year that I've been here he's improved slightly every year," assistant DBs coach Sam Garnes said. "And this year he made a big jump." A special teams standout, Bruton has never been asked to play much defense in his four seasons with the Broncos. He could push SS Mike Adams for the starting job this summer, but it's unlikely that Bruton will unseat him.
