We should see a nice progression in the offense with Goff. Kupp was older for a rookie and worked harder than most college players. I imagine he gets a little stronger. He did show he wasn't easy to bring down which was a little surprising. Mentally he has to focus on making the catch first. He tries to get going for YAC and doesn't always look the ball in. Overall he had a great rookie year and should be better in 2018.
