For the most part, rookie QBs are horrible. Josh Allen was horrible and really below average in most metrics in year 2 also. Then he became Josh Allen.I don't buy any of this talk, at all, personally.
Trevor Lawrence came into the league and his backup was CJ Beathard (who was in his 4th year, and had started 12 games for SF over the prior 3 seasons).
Josh Allen, came into the league, and in week one, they benched Nathan Peterman and brought in Allen, who then started every game since (except when he was hurt).
Jalen Hurts came into the league and sat on the bench, and got to spend almost a whole season watching Carson Wentz suck ass (not sure how that helped him).
Joe Burrow started immediately, and I'm not sure Brandon Allen and his 3 career starts at the time, was some real veteran presence/confidante for him.
Every situation is different, every player is different, and while Tua had Fitz, and Mahomes spent a year behind Alex Smith, I don't think there is any one size fits all model for any of these young QB's. IMO, the single most important thing for getting a young QB successful is getting them reps in practice, reps in games, and building a team around them with a good offensive line and good playmakers.
Hope folks are prepared for that. Some of the Zappephiles here might be calling for him again when the new kid has a 4 TO game. Depending on the kid though, still might be the right call to start from day 1.
Edit: please get him a fucking tackle though.
