Hornqvist is a good player, but I don't know how people can simultaneously advocate for changes while saying that every good player shouldn't leave.
Crosby, Malkin, Marino, Guentzel, Zucker, Kapanen, Jarry and Tanev (because they just signed him to a massive deal and wouldn't trade him this quickly) are not going anywhere. Guys like Lafferty, Riikola, ZAR and Ruhwedel have basically no value and don't really count as "change". Bjugstad and Johnson would be moved as cap dumps, I wouldn't count that as a change either. That leaves Rust, McCann, Hornqvist, Blueger, Dumoulin, Letang, Pettersson (who I'm tempted to include in the 1st group for the same reason as Tanev) and Murray.
JR wants change and people here want to make changes. "Changes" are moving players from the group of 8 I listed. Trimming the fat and getting rid of players you don't like aren't "changes".
