Above is the Ohio State schedule. The spring quarter ended June 1st. Final Exams are next week and the Commencement is on June 10th.
I'm just guessing, but he should be available for the final spring session on I think June 12, 13, and 14.
This would be a big plus for both him and also us fans who would like to see him. He would pick up a lot of valuable stuff to work on prior to the TC and us fans could get a look at him on the official site [steelers.com] which has an excellent video player and is covering the OTA's really good. Frankly I'm surprised. I think the coverage is even better than it was on FSN [Fox] before they decided to cancel the Steelers. [I have not watched that channel since]
I don't know if the link works. I really only wanted to copy out the 2012 spring schedule but instead of it going across the page in 4 columns it went in single file possibly ended up somewhere near Toledo Ohio so I put the link there.
Incidentally, Ohio State has now gone on a semester type schedule. This spring quarter ended that system. There probably will not be any problems for their players to be at NFL spring practices in the future.
