1. Do the 49ers have enough on offense?
The Niners' sloppy 9-0 victory over a hapless Washington Redskins team in a driving rainstorm at least somewhat captured where they are during their 6-0 start. On defense, they are great. Adding Nick Bosa and Dee Ford at edge rusher and Kwon Alexander at linebacker has made them one of the best defenses in the league.
But where are they on offense? They lack a No. 1 wide receiver, even though George Kittle is dynamic at tight end. Kyle Shanahan has put together one of the best running schemes in the league, but it's hard for them to keep their top backs, Matt Breida and Tevin Coleman, healthy. You also have to worry about injuries along the offensive line, as tackles Joe Staley and Mike McClinchey have been hurt.
Will they be able to score enough to navigate a five-game stretch in November and December that goes Seahawks, Cardinals and Packers at home followed by the Ravens and Saints on the road?
We could be asking the same offense question about the NFL's other undefeated team, New England, who also have injury issues on the line and limited pass-catching options.
