The Denver Broncos zone blocking scheme really should have a fullback that can handle a serious load of blocking assignments. Gary Kubiak and John Elway hoped to have found that guy when they drafted former Nebraska Cornhuskers fullback Andy Janovich.
Fullback is no longer considered a necessity by a majority of the league today. Many teams won't even carry one on the roster. However, Kubiak loves running the football and his offense still relies heavily on a fullback to open up those running lanes. Enter Janovich.
