During a period where both World titles changed hands a combined 412 times, you get both straps changing hands seven weeks out from WrestleMania, and with one man involved in both changes. Edge dropped the WWE Championship in the opening Chamber match after a stunning matter of minutes, only to assault Kofi Kingston and replace him in the main event, winning John Cena's World Heavyweight title. Convoluted booking aside, these are among the best Chamber matches in WWE history. That's particularly true when the first one comes down to Triple H and The Undertaker. RECOMMENDED MATCH: The first Chamber, with Triple H winning the WWE Championship. It's without question the best match to ever involve Vladimir Kozlov. I'm not exactly going out on a limb here.
