Someone offered him to me for a 2nd. I wasn't interested in giving up a 2nd for him. And I'm a Jags fan. He was a QB/gimmick player in college. I'm not a fan of players switching positions once they get to the pros. Never seems to work out for them. Jacksonville doesn't have much invested in him either (wasn't he a 6th round pick?). I don't trust they would keep him at the role he is in now if they had other options. I suspect he will be replaced by a shiny new toy next year. But with all the RBBCs in the NFL now, he will probably maintain some sort of role so he could have value there. I'm just not in the group that thinks he is worth a 1st rounder. But if you could get one, especially with his perceived value on the rise, that would be a major win for you. Just my opinion. He's also on the smaller side which concerns me some. He's not used to taking hits that a typical RB takes...but that could be something in his favor.
Hines Ward was a QB in college. First name that came to mind. And while switching positions upon reaching the pros is relatively rare, there are lots of guys who switched positions in college- typically from QB to something else. John Lynch and Anquan Boldin were both former quarterbacks. Ryan Tannehill was a former wide receiver. Jordan Reed was a quarterback for a while. Again, just a few names that come to mind.
Edit: Mike Pouncey played some defensive tackle in college. Matt Lepsis was a TE in college, got moved to OL when he came into the league, and started 9 seasons at right and left tackle for the Broncos. Shannon Sharpe was a college WR who was too big and slow to play the position in the pros. Mike Anderson switched back and forth between RB and FB. If I'm mentioning a lot of Broncos, that's just because that's the team I'm most familiar with- I'm sure fans of other franchises could give more examples, too.
