MADISON, Wis. -- There are brief, passing moments in which Tyler Marz's mind can't help but consider the worst about the health of his fellow offensive linemen. He has started every game this season at left tackle for Wisconsin, and he is the lucky one. Injuries have ravaged the line so severely that no one else on the team has played the same position each Saturday.
As casualties mount, doubt occasionally creeps in.
"You get to this point where there's not much depth and you kind of wonder, 'What if?' or 'What is next?'" Marz said.
