Sorry but the only true untouchables I see on our team is
Alex Pietrangelo and Vladamir Tarasenko
Anyone else on our team would be gone for the right price. (Obviously Pie and Vlad would be too but would be something completely unrealistic such as Crosby, and no I'm not saying they are worth that but its what it would take to pry them away from the Blues right now)
But players I think most likely wouldn't be traded would be
Pietrangelo
Tarasenko
Backes
Oshie (as another poster has stated, he is loved in St. Louis and brings in cash when it comes to fans buying something with his name on it.)
Perron (Young and our most talented forward right now, plus he is my favorite player and wouldn't really give him up for anything.)
I guess you could add Halak but if you have a halfway decent goalie coming back, he can go quite easily.
