Aside from Evans, none of those players were significant contributors last season. But it does hurt our depth among pass catchers and along the lines. Other items of note include Bordner officially being listed as a Wide Receiver and all the early enrollees getting numbers and official measurements.
All the attrition is natural. There will probably be more departures after spring and summer. As long as we don't lose key players, this won't set BC back. In fact the scholarship churn just enables Addazio to bring in that many more recruits in this next class.
