I meant that perhaps he isn't being trained away from this habit sufficiently. Not that he is being trained to do it. Also I assume Aranda was advised by both the QB coach and the OC as to who should be the starter.
Pros often do this stuff in pressure too. The player needs to own the coaching first and foremost, and planting feet is like one of the most coached items in any QB room.
The troubling piece about Shapen's development is that he hasn't shown a consistent improvement in controlling his body, specifically his lower body, under pressure. The game is just not slowing down for him right now, and his YPC shows you he's become addicted to check-downs. He doesn't stick in a shrinking pocket long enough to make downfield throws. Some of that is our WR group being underwhelming, but some of it is Shapen just lacking decision-making confidence.
When the pocket starts constricting and his first read or two are busts, you can just feel the panic in his body language and he starts tap dancing. It's frustrating because he has the arm to put the ball anywhere he wants it, but it seems like he can't settle his mind and slow the mechanism.
