Find out this week's players to watch, key matchups and a prediction of who'll prevail on Sunday between the Arizona Cardinals and the San Francisco 49ers.
The Arizona Cardinals' first division game of 2015 comes at home against the rival San Francisco 49ers. Similar to the Chicago Bears last week, San Francisco has a new look this year with a new coaching staff in place.
One thing that hasn’t changed is QB Colin Kaepernick, who will likely be the key to the 49ers’ success this season. Kaepernick has fared both good and bad against Arizona – struggling mightily last season on the road in Arizona.
