so firing sullivan imo, doesn't make sense right now.
give him competent goal tending.
better complimentary pieces for the 3 and if results aren't there then fire him, that seems to make the most sense to me.
while sullivan might have some blame in all this, the supportting cast got worse by a lot, our goal tending already was iffy and it got worse as well. I also argue our defense is older, slower and worse then it was as well.
Pretty much every move that Hextall made (or lack thereof in the case of goal tending) to make the team "better" for this season was actually code for "much worse"
