This is beyond Dak. As far as about winning anything, look at the 4 QBs from last years Conference championships, Bortles, Keenum, Foles. The most common denominator for a winning team isn't the QB, it's the defense. To win, you have to have a good defense. Eli isn't a great QB, he's led the NFL in INTs many times, Cam's been to a Superbowl he's a running QB and not particularly, accurate, Manning was a shell of himself and benched during the season for Osweiller, Flacco and Kaep, the list is long for average QBs going to a Superbowl, but you have to have a good defense and you have to be able to assemble a better team, regardless of who the QB is.
Even if we had a different QB, looking at the rest of this team, it is not nearly as good as fans think it is. People keep talking about building a better offense, but this FO has struggled much longer to build a better defense. Even if we had an elite level QB, this team hasn't shown the ability to build a better team. Over the years, some of it has been lack of talent, but also a lack of coaching.
