Prediction Wednesday: Ravens continue to defend home turf

What a Thanksgiving Day slate the NFL has this season. All six teams playing Thursday won on Sunday.

The game I'm concerned about, of course, is the nightcap between the Baltimore Ravens and San Francisco 49ers. I think this one could be a very tight game.

Both teams are very good defensively. The Ravens, though, can move the ball through the air if they have to, while San Francisco is more of a grind-it-out team. 

I think the Ravens' quick-strike ability will be a key factor in this game.

Joe Flacco's arm, along with Torrey Smith's legs will be the X-factor. 

Another factor in this game will be the cross-country flight for the 49ers. The flight in itself will be taxing on the players.

I think the score will be 17-10 Ravens.
