I think that Grits, Rusty, and zn were all correct, each in their own way.

Our passing game is a bit like a 3 legged stool.

QB
Receivers (both WR and TE)
Coaching

An easy case could be made that the Rams were lacking in all 3 areas last year. No wonder we finished in 32nd place.

The good news is that it appears that all 3 areas were addressed aggressively.

Goff
Too many new WR's and TE's to list individually, but lots of positive camp reports have come out.
Mike Groh (possibly our second best offseason acquisition)

I mean, recent camp reports are pretty danged encouraging in all 3 areas.

So... Perhaps our 10 year O nightmare is now over? I'm cautiously optimistic.

BTW, I should also acknowledge the upgraded OL. (It just didn't fit conveniently into my 3 legged stool metaphor.) Lol.
