On June 28th, The Daily Clipper
listed an article from the ESPN Knicks Blog that might have been related to the information on this link from foxsportsflorida.com, but the ESPN Knicks Blog did not mention the talk of Olajuwon potentially tutoring Griffin.
According to the link, Griffin is one of the players Olajuwon would like to bring in and tutor. There was talk of getting Griffin to see Olajuwon during the 2011-2012 season, but things did not materialize (probably due to the compressed season). The session(s) could potentially happen this offseason.
Check out the article for more on a potential Griffin-Olajuwon workout and Olajuwon's quote on what he thinks of Griffin's offensive game now and how he can improve. The link also contains quotes on Olajuwon's evaluations of other players.
