Yes your post was a "poster child', not you. Reread my post and stop taking things personally. They are not my models, they are universally accepted models used by everyone.
Yes every mathematical model can be skewed - that is why there are various ones to pick from. To say a guy with a 59% completion percentage, 1TD, 1 INT, and 7 YPA is anything but below average is an emotional judgement. You claim Heinicke was very close to his receivers when he missed them - that is a miss. Of course the press says glowing things about his performance, he lost, they are not going to sh!t on him after that.
Heinicke was on the Pats' 2017 practice squad and the coaches let him go. Stidham has been on the active roster for 2 years, and is still here. You want to start Heinicke because you know better than the Patriots' coaches? People justifiably question the Pats' draft picks, but the number of guys that the Pats cut off the roster or practice squad that rose up to star on other teams is miniscule.
Heinicke is great guy, and a great story. More inaccurate than Cam Newton, who had what some people say is the worse supporting cast in the NFL, and you want to being Heinicke in to play for the Pats. Because of your eyes.
