Personally, I like Shugarts and Adams better because they are true OT's. Talent-wise, I'd rank them as follows: Adams, Shugarts, Hall, but they are all excellent prospects. Hall needs quite a bit more "polish" than the other two, so I guess that you could say that he has the greatest "uspide" of the group.
1. It is difficult for any true freshman to start at any school.
2. It is even more difficult for a true freshman to start at a "stocked" program like Ohio State or Southern Cal.
3. It is very difficult for an offensive lineman to start as a true freshman because they usually need at least one year in a college system to work on (a) strength and conditioning; (b) technique; (c) learning the playbook; and (d) adjusting to the "speed" of the college game.
4. It will be very difficult indeed for a 2009 true freshman OL to start at Ohio State, with the likes of Cordle, Adams, Brewster, Shugarts, Boren, Smith, Blankenship, and Browning all on the roster.
5. So, to answer your question, it is possible, but unlikely, that Hall could start as a true freshman at Ohio State.
No.
