The Green Bay Packers will play the San Francisco 49ers on Sunday in one of four late afternoon games in Week 4 of the NFL 2015 regular season. The Packers will be looking to make it four straight wins today, and will be favorites to do so against a troubled 49ers team still just on one win so far this season. The game has a start time of 4.25 p.m. ET and takes place from Levi's Stadium in Santa Clara, California.

Prior to the regular season getting started, many pundits had predicted that the 49ers were a team that could go in either direction this season. They are a team packed with potential, and if they started fulfilling that potential they could be real competitors. However, they are also a team in a transition in many aspects and are still trying to find their feet, and in that aspect this season may be too early for this team to truly compete with the best in the NFL this year.

After three weeks of the season it certainly seems that the 49ers are going in the latter of those ways. After getting their season started with an impressive win over the Minnesota Vikings, there was a sense of optimism in the 49ers camp.

However, what a difference two weeks can make, and in that short space of time the 49ers have allowed a massive 90 points to be scored against them, and look like a team in disarray.

San Francisco have had serious problems cruelly revealed on both sides of the ball, and this week they come up against Aaron Rodgers and the Packers, and that means things could go from bad to worse for the 49ers today.

If Carson Palmer and Ben Roethlisberger could so easily take apart this San Francisco defense, then 49ers' fans will shudder to think what Rodgers might do to them today if their team is not at their very best.

Earlier this week, Thursday Night Football saw the Baltimore Ravens snap their losing run. The Ravens, entering the nationally televised game on 0-3, managed to steal the win in overtime, to defeat the Pittsburgh Steelers 23-20.

The game had looked like the Ravens were in for another painfully close loss. Over the opening three weeks they had lost games by small margins, and often because they had lost concentration for a period earlier in the game, and simply could not get over the line in their fight-backs.

In the second period in their game against the Steelers they looked like they had done the same thing, allowed Pittsburgh to pile on 10 unanswered points. Coming into the fourth quarter 20-14 down it looked like the Ravens were heading for another defeat and would move to 0-4. However, they finally managed to complete their fightback after failing three times already this season.

The Ravens pulled the game back to 20-20 late on to send the game to overtime, and with momentum on their side, they finally got over the line and completed their first win of the season. That result probably damages the Steelers more than it helps the Ravens though, but the game was a perfect way to get Week 4 underway, and now on Sunday there will be 13 more games taking place as the season becomes even clearer as to who will be competing and who will be falling down this year.
