QUARTERBACK
Who's back: He has thrown a grand total of 15 passes in his collegiate career so far, but that number doesn't quantify Oregon's faith in sophomore quarterback Tyler Shough. And much of that confidence is rooted in traits that are hard to quantify as well. When the Ducks open preseason camp on Oct. 9, they'll do so without four-year starter Justin Herbert, whose stature, arm strength and underrated athleticism were measurables that had NFL scouts agog. Shough — rhymes with "Duck" — may still be maturing toward those levels of physical gifts.
