Funny. I fired it up last night too and had a blast playing. As much as I have played and tolerate NHL 13, I just really have so much fun with this game, and NHL 2k11 as well on the Wii.
Anyway, I haven't encountered any freezes in my franchises or anything. There is a roster glitch somewhere but I forget what it does, I'd search it. It may only come into play making new rosters though and not affect franchises.
The other thing is in year 2 and beyond in franchise you'll have to manually edit the new drafted goalies to the goalie edit so they play better. They received a major global edit a few years ago, here is the link if you're bored, lot of fun
(HERE).
The breakaways were minimized by editing the teams' strategies. Stay Back, Cautioned and Balanced are the only 3 to use. All out and aggressive don't work.
I'm also thinking of a restart in 2k10, or even 2k11. Played that on the Wii yesterday with the classic controller and as ugly as it is on Wii it played sexily!
Also, if you plan to play online coop franchise like I do with my buddy. You must make sure that the teams playing have a 23/23 roster or lower 22/23 is ok. Some teams end up 24/23 and that causes a freeze and disconnect EVERY TIME! Enjoy
