Blashill is great until the first time he trots out lines people hate. Assuming he gets the job, he will do good things and bad things. People will disagree with him. In the end I doubt he's better than Babcock even if he gets a bit better results. Even if the players are mostly the same next year, which is likely, young guys will be a year more experienced, older guys will be a year slower, meaning it won't be the same team.
We might as well not even watch next season.
