I agree, but I will explain. I think Stafford's ceiling is higher than Goff's, but because he takes so many chances, his floor is lower.
Goff was much more cautious and would become even more so in an intense, physical game like today. He could be downright ineffective.
Stafford can make some brilliant throws, but then on the next drive, he can miss badly to the point where people wonder if there is something physically wrong with him.
I like Stafford, but I wish the Rams hadn't given up so much to get him. Their offensive and defensive lines need a lot of work.
