Shero went all in, but moving prospects and picks (as much as I hated the Morrow deal) is not as comparable as moving a burgeoning young blueliner with back to back 60 point seasons, your leading scorer who was on pace for 100 points, a great young winger who put up 113 points the year before, the best offensive blueliner in the league, etc etc.
No one was safe with CP at the helm, save Mario. If you were damaged goods like Stevens, bye. Your play started slipping like Tocchet or McEachern, bye. These guys were big parts of their SC runs, but CP didn't let feelings get in the way.
It usually paid off though, except in the Naslund case. He turned Stevens, Tocchet and McEachern into Lucky Luke, Smokes, Murray, into Kovy, Zubby (who he didn't hesitate to move for Hatcher), Eddie O, Kaspar, etc.
Shero doesn't take big risks like that and I think people need to realize that. People think he will move Letang and the reality is I doubt he would even move Orpik. It's just how it is. He will fix holes and try to make his team better, but he will remove as much risk as possible while doing it.
