I think you're right. And I expect Kendricks and Higbee to represent a nice 1-2 punch in the passing game. Lance looks like a different TE, he's really smooth and seems like he's finally figured things out. Higbee is fighting history, where rookie TEs rarely make an impact (even the greats), but I do think he has the hands and natural receiver instincts you want and I suspect the Rams are going to scheme him for matchups.
The pieces are there for a solid passing game. We don't need the GSoT to win a ton of games, just a low error offense that can take advantage of field position flips as they come from the defense and Gurley/Tavon.
