Osweiler is the QBOTF. but you need depth and you want to gain that depth and have it developing before Manning retires. this way you have guys who have studied under Manning and learned from him. you don't wanna have cold rookies or new starters coming into the fold and needing mentoring like some other franchises do.
if Os pans out it allows us to maintain a certain level of success even after Peyton retires and it allows us to have solid depth at the position and not to have to go through what we did when Elway retired.
i can see us taking another QB next season depending on value and how Dysert develops.
i personally think Dysert will end up being a super back up for us who will give us leverage to make improvements elsewhere and get good draft pick value for in the future.
