How much of this though was how the coaching staff dealt with Parsons? I'm sure Mertens saw how Parsons was pretty much shipped out of the QB position because he was a run first QB. Whether it was what the coaches told the QB's or just observing that, I'm not surprised at all that Mertens was a QB this last year who was a scramble to throw instead of a scramble to run.
I honestly don't know if Mertens is the QB to lead us next year or not. But I sure would like to see him play a few games with an offense suited to his strengths instead of running the same offense as what Walker ran.
