The identity of the 2013 Notre Dame offense instantly changed in drastic fashion when former starting quarterback Everett Golson was dismissed from the university for academic misconduct.
Both Golson and current starting quarterback Tommy Rees bring a unique skill set to the table, though each causes the Irish offense to operate in a different manner.
The challenge for Notre Dame head coach Brian Kelly is transitioning from a Golson-led offense to a Rees-led offense.
Through the first two games of this season, that transition has gone smoothly.
But with Rees set to see his eligibility clock expire following the current season and Golson slated to return to Notre Dame, Kelly will face yet another transition entering the 2014 season.
Comparing these two offenses has been a common point of discussion during the past calendar year, and it continues here.
