Most quarterbacks in the league are game managers. There are maybe only 4-5 quarterbacks in the whole league who can succeed without a strong running game or with poor offensive line play.
This board seems to expect Bryce being a first pick, to perform like Joe Burrow or Josh Allen, but there are only two players like them in the world and Josh Allen didn't look like Josh Allen in his second year.
Lastly, and most importantly, this is the situation we have. It does none of us any good to complain about what Bryce isn't because, unless everything goes disastrously wrong, he is here for the foreseeable future and is highly likely to be the starting QB. You can bring in all the QBs you like, but everything is slanted towards Bryce because he was their choice at QB and because of that, they are going to give him every chance to succeed.
