I'm following the lead of colleague Brian Bennett and taking a look at some of the key players lost from each team in the ACC and who the players were who replaced them this spring. We'll go in reverse alphabetical order, starting with the Deacs:
Biggest shoes to fill: Center Russell Nenon
The four-year starter was the anchor of the offensive line and is a potential NFL draft pick. The veteran was athletic, tough, and like a second coach on the field. He was also able to play guard and played despite injuries as a senior. He started every game his final three seasons, and during that span, it was easily the most secure position on the entire team. Nenon was the best, smartest offensive lineman the Deacs had. The staff went from not thinking about it to it becoming a position of concern.
Spring replacement: Redshirt junior Garrick Williams.
Summer outlook: Williams is the undisputed heir to Nenon, but he needs to get stronger and will only get better with more experience. Williams started three of the final four games of the 2010 season, and played a different position each time. He played earlier than the staff would have liked him to because of injuries, but he's still not an established player and struggled to snap the ball at the end of spring practices.
