Unless NFL teams are talking to his "advisors" about 1st a round selection (and the money that comes with it), I would like to see him stay in school. He needs more time.
Next year will be very interesting for OSU. IMO, if JT Barrett can stay healthy, he projects better as a next-level QB (better at reading defense and seeing third route receiver), but Cardale Jones fits MUCH better into the Urban Meyer offensive style (big body, big arm). Braxton Miller needs to transfer to Oregon. Tough break for him, but that's life.
