Oakland Raiders rookie running back Josh Jacobs has gotten his NFL career off to a terrific start, as he has rushed for 430 yards and four touchdowns while averaging 4.9 yards per carry through his first five games.

Most recently, Jacobs even tore up the stingy Chicago Bears' defense for 123 yards and a couple of scores.

Now, the 21-year-old will get a shot to do more damage this Sunday when the Raiders take on the Green Bay Packers.

The Packers' defense was lauded earlier in the season after allowing just 19 points combined in Weeks 1 and 2, but since then, it has come crashing back down to earth.

Green Bay's defense now ranks just 21st in the NFL, and against the run, it ranks 23rd.

So, if Jacobs was able to rip apart a Bears defense that is allowing just 83 rushing yards per game, imagine what he can do to a Packers squad that is surrendering 124.5 yards on the ground on a weekly basis?

Of course, nothing is guaranteed, but if there was ever a time for Jacobs to have a big game against a really good team, Week 7 seems to be it.

Oakland has been surprisingly solid thus far this season, going 3-2 over its first five games, and much of that is due to the performance of Jacobs, who has logged 8.3, 4.4, 4.7 and 4.7 yards per attempt, respectively, over his last four contests.

Remember: the Raiders' offensive line has improved significantly this season with the additions of Trent Brown and Kolton Miller at the tackle spots, so Oakland's ground game has a lot more room to breathe than it did a year ago.

It helps having a very talented running back in the backfield, as well, but the fact that the Raiders' offensive line can do things it could not even come remotely close to doing last season is also pivotal.

Of course, Jacobs will need some help from Derek Carr in order to keep the Packers' defense honest, and outside of a dreadful outing in Week 2, Carr has done that throughout the season, as he has completed a league-best 73.3 percent of his passes.

Carr hasn't put up huge numbers, throwing just six touchdowns through five games, but he has managed the game well enough to give Jacobs an opportunity to succeed, and if Carr does that again this Sunday, the Packers could have their hands full with the first-year back.

Whether or not the Raiders can actually summon the strength to beat Green Bay is another story, but don't be surprised if Jacobs has a big performance regardless of the outcome.
