Is it really that simple? Sure, Siemian had some time to throw the ball at times. At others, he was under duress. The difference between him and Fields is that Fields holds onto the ball, tries to wiggle free or run (sometimes leading to sacks), while Siemian just gets rid of the ball before a sack could be registered, often incomplete or a short throw for a minimal gain. This might be an argument if Siemian's not-taking-sacks ability led to actual offensive success then we would have had more than 10 points.
