Can the Kansas City Chiefs expect these stats to continue?

The reason many people are mocking a receiver to the Kansas City Chiefs is because the offense has to get better. From that standpoint, the following Chiefs stats won't be a surprise to you but I found them interesting anyway.

Only 53.7% of the #Chiefs TD drives were 60 yards or longer. League average was 71.6%, no other team below 60%. Monster discrepancy.

Indeed, that's a large discrepancy. Why was that? Because the Chiefs had the best starting field position in the NFL, which led to shorter fields. That came through an NFL record in kickoff return average and one of the NFL's best turnover margins.

#Chiefs also had 10 TD drives of 29 or fewer yards. No other team had more than 8, league average was 4. Turnovers/ST a big deal.

Now, you can't blame the Chiefs offense in 2013 for these stats. They took advantage of the opportunities provided to them. Assuming the Chiefs don't lead the league in turnover margin and they don't have the NFL's best starting field position next season -- those things vary so much from year-to-year -- they'll need their offense to be better in 2014.

It's not so much that the Chiefs offense was bad in 2013, it's that they can't expect to be so far ahead of the league average in stats like turnover margin and starting field position next season. So they'll need a better offense to compensate for that.
