Tomorrow, the NHL goes crazysauce

So, tomorrow is the open of NHL Free Agency. There will probably be 100 roster moves tomorrow alone. That's crazysauce, right?
I'm wondering why it's not like this in other sports? Why does it take an entire offseason for players to sign and move teams? I bet within an hour, there will be 20 players signed to ostentatious new contracts. Too bad the NBA Lockout has to start on the same day, otherwise you would hear all about where Brad Richards  will end up.
Wait. Brad Richards is the top of the class this year? Psh, Lame. And on the "All free agent team" by TSN has Anttie Miettinen on the 2nd line? Holy awful.
As you were...
