This doesn't seem to be a good QB year in the draft, so that likely means all the prospect will get overdrafted this year. That doesn't create a real good environment to maybe get someone on the cheap that has NFL skills that you can develop behind Ben.
If there is one prospect that maybe we should talk about and is outside the box is Chad Kelly. First, even in a QB-thin draft, he has two big knocks against him right now. First, he had ACL surgery in November and will not be ready for (likely) all of OTA, training camp and the early part of the season. Second, he has some off-field baggage and immaturity issues (he was kicked off Clemson's team, arrested in a bar fight, etc.).
Now Kelly might have more talent that your typical late-round QB. He is Jim Kelly's nephew. And Bill Polian supposedly vouches for him as person, even with what happened. I mean, I suspect Jim Kelly was big partying at Miami in his day and he chased the big paycheck in the USFL and finally matured into a pretty decent human being and success in Buffalo. Could Chad Kelly follow those footsteps from southern college party school to cold-weather blue collar city? Maybe.
And maybe Pittsburgh, the Steelers organization, and having Ben help him grow up could work. I've heard of wackier what-if scenarios.
So if you are going to talk about a better option than Landry Jones but don't want to spent a premier pick on a QB prospect while trying to win a Super Bowl in the next three seasons, Chad Kelly might be the best option in this draft.
