He's far from trash, few people would succeed in that team.
But let's be honest, a lot of his low INTs come from him keeping it safe and taking sacks. And a majority of the sacks I've seen are not due to bad o-line, it's cause he doesn't know how to throw it to the sideline or take calculated risks.
But again, 1st year QB with a lot of trash in the team, even moreso in the coaching staff and in the FO.
