Yeah, I've been this board's most ardent Sullivan defender, but the recurring blown leads is all on the coach. The only explanation for an issue like that is that there is a disconnect between the coaching staff and the players on something, and that means it's entirely on the coaching staff to fix that problem.
The fact that it has not only happened this often this year but has been a recurring issue for a couple of years is pretty damning for Sullivan.
At this point, the only reason he's around has to be because of the core and they don't want a coaching change this late in their careers.
