At the risk of sounding like an idiot, any NFL team should ALWAYS be in the business of developing a QB. If the team in question can't draft a QB to develop, then the developmental QB ends up being an UDFA (mostly by default). Not doing so is how the Bears have ended up having to overpay for an average to average+ QB. It is also how the Bears have ended up with O-linemen who don't have to compete for their starting jobs. Which is how the Bears have ended up with an O-line that ranks in the bottom third (at best) in the NFL.
