He's a much more talented player. What do I see in the preseason? A much more talented thrower.
Do you think Goff would have looked different tonight throwing to our first team WRs, TEs, and HBs with the starting OL blocking for him? I certainly do. Goff managed to drive us down the field for a FG against Denver's starting defense with our SECOND-team offense. Enough said.
Keenum is what he is. He's a limited game manager. Goff will make more mistakes than Keenum. But he will also offer much more upside than Keenum on every play. He opens up our offense in a way Keenum doesn't.
