Even though I'm worried about our offensive staff and whether they're up to snuff, I think Goff is going to be like Manning in that he'll work his butt off to translate what is taught and know it cold, execute it well for a rookie, and run a solid offense. So I think he wins the job right out the gate and plays well, prompting teams to view the Rams with envy.
22 - 14 is about what I expect for the TD/INT ratio. He's going to be playing with a good defense and run game and the Rams always have good special teams, so will have some nice field position flips in his favor. If the defense ends up top five then I think he might get more TDs. If they're middle of the pack then less.
3.2k yards is about right too. Yards aren't going to be the key for this guy because they're going to be very balanced. 3.5k is possible, which is what Bradford did in a mediocre offense his rookie season. But again I think balance works against him on the yardage and I am ok with that.
Completion percentage should be a little over 60%. This one's dependent on his receivers. In a best case scenario where Tavon and Britt improve with a better QB and both Higbee and Coop step up right away to contribute I think he could end up a point or two higher. Higbee is a really big part of the equation IMO simply because he's such a big target with good hands and Goff is so accurate. Having a TE like that can really boost a QB's comp percentage. But I expect him to be about 61%.
