The fears of returning to a ******, pre-Sullivan 4th line are completely unfounded.
Even if that does happen, and we start the year with some crap like Kuhnhackl - McClement - Reaves, and they suck ass and the team is worse off for it, we know that JR is absolutely not afraid to admit a mistake and make it right. And that's assuming Sullivan wouldn't do it first and call up Blueger, sit Reaves for Archibald or whatever else is in his arsenal.
I think we should probably expect a dip in total offensive output from the 4th with Cullen gone, but I don't expect it to be any less effective. Hopefully more-so. I understand, Gladams is still in our memories, but that's not going to happen again. Neither JR nor Sullivan will let it.
*If* McClement gets a contract, it'll only be because he earns it in camp, and even then he'll still have to earn his spot in the line-up every night. Sullivan isn't going to put up with ******** if there are better and more productive players in the press box or in Wilkes-Barre.
