Kane might get extended but I cant imagine Toews signing another contract anywhere. He'll probably retire
Toews would have to sign for something like 2-3 million at most for a year. So essentially I agree, he will most likely just retire. I think it would be the right move, the guy has won at every level and his concussion history is no joke. That's hard to say, but it's true. He'll go down not only as a champion at every level, but as the greatest captain in Blackhawks history.
Kane, same story, but maybe he gets offered a bit more for one year, like 4-5 million perhaps? Unlike Toews, who always played a harsher two-way style of hockey, I do think Kane still has more hockey left. The question will be, will he want to stick around on a shit team on a short-team deal -- he has said he wants to stay in Chicago, but of course, every player says that. Maybe he will want to continue to rise in the Blackhawks record books, that would really be the only reason for him to stay.
I remember on the Blackhawks old board (when they had one on their main site), maybe around 2013, we argued which players would have their numbers retired. Many posters, myself included, listed like 4 players, lol, many of which were the same and ranged from Hossa, Toews, Kane, Keith, Seabrook, Sharp, etc. And these posters weren't newbs, they were veteran posters. I guess we all just got blind in that era of dominance, considering how rare it is for one number to be retired, let alone multiple numbers. It's funny in hindsight, how naive we were. Now, it's hard to see anyone up in the rafters other than Kane. These are all great players/champions, but in order for your number to be retired by a franchise, you have to be an utter legend for your entire career.
