It makes sense, not just because we play them next, but some people have called Heinicke a "poor man's Russell Wilson".
So, how meaningful would it be, to beat the guy you're compared to in that manner
In Heinicke's mind, during the course of his future career, he probably wants to erase "poor man" from every comparison about him.
I'm not saying that beating Wilson puts him on the same level, I'm just talking about Heinicke's mentality to do everything he can to prove the naysayers wrong.
