From Moranis:
There are plenty of teams that might have been interested if they think Jones projects out like Big Ben. I mean a team like Cincinnati that has Dalton, who is good, but not great might take a flyer on a guy like Jones who could be great in a year or two. So they ride Dalton until Jones is ready. Denver could use a Manning replacement. New England has Garoppalo (or whatever his name is), so they are probably out. If one of the teams that needs a QB misses out on Jameis or Marcus, I could see them taking a flyer on Jones in the 3rd round. Heck even the Browns make some sense.
It is all moot now since he is going back to Ohio State, but I easily could have seen him going in the late 2nd round. He is 6'5" 250 pounds with a cannon for an arm and is mobile enough to make things happen, but not so mobile as running is his first instinct. And sure he only has 3 games, but he looked pretty good in those games. He for the most part read the defense well and made the right throw even if he wasn't always on target. And how much more film is going to be useful in an offensive system like OSU has. I mean it isn't like Jones is taking the ball under center and running a pro style offense. Sure more games gives you more film, but there aren't going to be many similar situations even if he had started all year. That is the problem Mariota is going to have and why his pro day is going to be so important for him. He needs to show the scouts he can run a pro style offense (that isn't Chip Kelly's).
Of course you could have. You could easily see a whole 1st round of Ohio St players.
