Division finals live chat: East Final sees Ray-Calvillo showdown, while Glenn steps in out West

Sunday sees two crucial division final games that will determine who advances to the 100th Grey Cup in Toronto next week, and 55-Yard Line's your home for full coverage of both games. We'll be live-chatting throughout both games right here. Both have a surplus of compelling stories. In the East Final (televised live at 1 p.m. Eastern on TSN in Canada, tape-delayed to 11 p.m. Eastern in the U.S. on NBC Sports Network), Toronto quarterback Ricky Ray will try and lead the Argos to an appearance in the hometown Grey Cup, but he'll have to survive the Montreal crowd and outduel another legendary quarterback, the Alouettes' Anthony Calvillo. With explosive players like Toronto's Chad Owens and Montreal's S.J. Green, this should be a high-scoring one. Out West, we may not see as many points, but we could be in for a fascinating game; Stamps' preferred starter Drew Tate is going to miss this one thanks to a fractured wrist, so that puts all the focus on veteran backup Kevin Glenn. Will he be able to continue the success he displayed in relief of Tate this season against the formidable B.C. defence?

Those are just the opening storylines, and there are plenty of other intriguing ones to consider as well. How much of a factor will both crowds be? Will B.C. quarterback Travis Lulay be fully recovered from his late-season injury? Who will win the battle of the Canadian running backs, Calgary's Jon Cornish or B.C.'s Andrew Harris? Will either the Argos or the Als be able to get defensive stops? Tune into the live chat below to find out. Things will kick off with East Final coverage at 1 p.m. Eastern.
