I think it may be a good decision. Right now, he would rank as my third rated OT behind Jake Long and Ryan Clady. If he returns for his senior season and has another outstanding year, he could emerge as a top 5 candidate next year.
Well, conventional wisdom says with all of the Junior OTs declaring for the 08 draft, the 09 draft will be pretty thin at OT. So Oher has a chance to be one of the most coveted prospects in the 09 draft, especially with a year under Markuson. It's a good decision for him.
