Quenneville doesn't need to be mentioned, that's obvious.
All Keith has to do is keep up solid numbers for the rest of his career and he's in.
Kane and Toews are early-middle in their careers still, but at this rate should make it. Two players that completely flip a franchise around and are as successful don't come around that often.
Hossa is a tough one. I used to think no, but am starting to think he'll make it. He has the numbers, the success, and the legacy as probably the strongest 2-way player in the league for quite some time. We'll see.
Seabrook I think someday will have his number retired by the Blackhawks, but will not make the HoF. That is, if he keeps his numbers up and stays here over time. He's been hugely pivotal to Hawks history and scored a buttload of massive goals.
19, 88, 2, and 7 all hang in the rafters of the UC someday. Hossa's a maybe since he hasn't spent a lot of his career here.
Smythe's excluded, i hope the lack of individual hardware doesn't keep Toews and Kane out. Unlikely, but still
You could argue that Smythes are the only truly important hardware. Along with Cups of course.
