I'm appalled that no one has posted this on the Chronicle yet, but the Thrashers have signed ex-Oil dude Marty Reasoner. Basically, he adds depth: he'll be a good 3rd or 4th line center and he's a good defensive player. If the comments at TSN are any indication, Oilers fans are sad to see him go.
The way I see it, we now have four official centers (Erik Christensen, Bryan Little, Todd White, and Marty Reasoner), two potential centers ready to go if needed (Eric Perrin and Jason Williams), and one in the system (Angelo Esposito). Not bad, really.
CORRECTION: Jimmy Slater exists and is also a center.
