Why are the Chargers that much better?

[synthesis2]

I know I'm going to get a lot of flack for saying this and I even put money on the under for the chargers and the over on the chiefs because of this but I just don't see where they are that great of a team, especially with the changes.

Comparisons:

QB Chargers - B/B+ (not elite) Chiefs C (average at best)
RB Chargers - B- Chiefs A (may have best in league with combo)
WR Chargers - C+/B- (with holdout) Chiefs C+/B-
Oline Chargers - B Chiefs - B
TE Chargers - A Chiefs - D/C ( still not sure on 3rd round pick)
DL Chargers - B Chiefs - C/C+
LB Chargers - B Chiefs - B
Sec Chargers - C Chiefs - B+
Spec Chargers - B Chiefs - A
coaching Chargers -C Chiefs - B (with new off and def cord)

I guess we will see Monday but I just don't see it with the Chargers this year, besides QB, they are very pedestrian and we are better in several areas.
