Divisional semi-finals live chat: Argos and Eskimos face off, then Stamps and Riders

It's the CFL playoffs, and our 55-Yard Line crew will be providing extensive coverage of every game. To kick things off, we'll be chatting live during Sunday's divisional semifinals. The action starts with the 9-9 Toronto Argonauts hosting the 7-11 Edmonton Eskimos in the East semifinal at the Rogers Centre (1 p.m. Eastern, live on TSN, tape-delayed to 4:30 p.m. Eastern on NBC Sports Network in the U.S.), a game that features Argonauts quarterback Ricky Ray and Eskimos running back Cory Boyd taking on their old teams. After that, it's the 12-6 Calgary Stampeders hosting the 8-10 Saskatchewan Roughriders in the West semifinal (4:30 p.m. Eastern, live on TSN, tape-delayed to 11 p.m. Eastern on NBCSN), which could be an entertaining showdown of top running backs Jon Cornish and Kory Sheets.

What's interesting about these games is that although the teams' records heading in are lopsided, there are some reasons to believe the road underdogs may have a chance. For one, there's the matchups. Out East, the Eskimos' passing offence hasn't been great, but they have plenty of rushing talent with Cory Boyd and Hugh Charles; meanwhile, the Argonauts' defence has been solid against the pass but has struggled against the run. That could give Edmonton an edge if they can keep the score low and turn this into a ground-and-pound contest. Out West, the cold temperatures (-13 Celsius at the moment, -20 with wind chill) may put further emphasis on the rushing game, already a strength for both teams. Both defences have been strong against the run as well, though, with the Riders and Stampeders allowing the second- and fourth-fewest rushing first downs and the third- and fourth-fewest rushing yards per game respectively. Those matchups should make for fascinating games. Follow all of today's CFL action with us in the live chat below.
