Thomas and Sanders are legitimate elite receivers, although DT is slowing down after all the wear and tear on his body.  The Broncos need a third receiving option, a better O-line and either C.J. Anderson or "other" to emerge as a 1000-yard plus rusher.  It is too early to assume the team won't develop this way.  But honestly, in the AFC West, I think the Broncos' offensive personnel isn't that much worse than the Chargers and it is probably better than the Chiefs.  Personally, I'd rather have a team that was strong in all three phases than one that relies too heavily on the offense or the defense.
