Trade Deadline

Today is the NHL Trade Deadline
Which, for major hockey fans, is pretty exciting

The Sabres are in a tough position. They are just out of a playoff spot and their 2 best players are injured (Vanek is supposedly coming back tomorrow, Miller is unknown). Should they buy or sell? They have 4 guys who will be unrestricted free agents at the end of the season (Connolly, Afinogenov, Kotalik, Spacek). Here's a list of guys I wouldn't mind them trading:
Kotalik
Tallinder
Paille
MacArthur

And I'd like them to get a big-tough center (1st or 2nd line type). We'll see what happens. If they trade for a goalie, that may mean Ryan Miller is out for longer than I hope.
