Sullivan could turn out to be a godsend. First of all, he's a proven Pro (unlike Groy).
Secondly he knows the offense and can help that o-line immensely from his position in the middle of the field.
Thirdly, we should get some very accurate line calls from him.
Forthly, he's only 31 and he's had a year to heal up properly any look good in that one game he did play in.
Groy, could have been a slight upgrade over Barnes but nothing was guaranteed.
Before we get too upset lets see if they can sign Sullivan.
