The NFL season is nearly a third of the way through and there have been two constants so far in the first five weeks – the San Francisco 49ers and Philadelphia Eagles are unbeaten.

Both teams picked up wins on Sunday – the Niners against the Dallas Cowboys and the Eagles against the Los Angeles Rams. The Eagles and the 49ers met in the NFC Championship Game last season and appear to be on a crash course again this year.

San Francisco defeated Dallas 42-10 behind four touchdown passes from Brock Purdy, including three to George Kittle. The 49ers are 5-0 and are second in points scored, third in yards gained, first in points allowed and third in yards allowed. They are going to be a force to be reckoned with for the rest of the season.

Philadelphia topped Los Angeles 23-14. Jalen Hurts topped 300 yards passing and had a touchdown pass to Dallas Goedert along with a rushing touchdown. Philadelphia is fifth in points scored, second in yards gained, 13th in points allowed and 10th in yards allowed.

The two teams have an NFC Championship rematch on Dec. 3, and if they are both undefeated at that time, it is certain to be one heck of a matchup late in the season.
