Arizona Cardinals vs St Louis Rams takes place on Sunday in Week 1 of the NFL 2013 regular season. The Cardinals will be looking with optimism at the new season hoping that it is the start of a new era for them, however, for St Louis this season is more a case of ensuring they keep building on what they already have and optimizing their roster.

The game is scheduled to start at 4.25 p.m. ET and can be watched online through live stream via the link provided below. The game can also be watched on television on Fox.

Both of these teams will be hoping their quarterbacks can prove something today as the season gets underway.

For the Cardinals, Carson Palmer will be the man the team looks to as they try and make this a positive season and hopefully sneak into the playoffs.

For St Louis meanwhile, Sam Bradford will be a pivotal figure as they try and navigate a maturing team to make the step up to a new level and begin to achieve new things.

The Cardinals have a lot to prove and will feel the pressure to finally deliver for their fans.

St Louis managed to win four of their last six games in 2012 and are looking optimistically at this new season hoping they can continue in the same form and improve more. They have one of the league's youngest teams, and if they can nurture the key players well they should have increasingly successful seasons over the coming years.

The Cardinals will hope they can get as good a start to the season as last year when they went 4-0. Of course they went on to lose 11 of the next 12 after that, but they still would bite your hand off to start 4-0 this season again.
