What would I give up for Malkin?
Do not want.
Guy can't play defense, can't play in key nail-biting situations, can't handle smothering coverage (he just went pointless in a sweep loss with probably the best supporting cast you're going to see in this cap era. And we all remember what the Wings did to him way back when.) And I don't get the sense that he's a great team guy, though that may just be me. Still, ultimately, Do not want.
"Can't play in key situations"
Uh huh. How many points did Datsyuk have in a 7 game series against Chicago?
