10/5/09 Rivlas article: Walker lists an offer list of Pitt, Georgetown, Kansas, Marquette, and A&M.
10/12/09 Scout article: Talks to Walker's coach. Walker has offers from Pitt, Marquette, Seton Hall, and A&M. UConn, Kansas, and Georgetown have not offered and they hope he waits until spring.
11/22/09 Rivals article: Jerry Mayers says, "The big fella didn't have much of an impact on the game as his minutes were limited.
Part of the limited minutes is due to his need to be in better condition, but there is no denying that he is a post player with impressive size and good skill set."
2/22/10 Zagsblog: Walker has a list of Marquette, St. John's, Pitt, Georgetown, and Seton Hall. Walker's dad explains that those schools have interest in Walker, but doesn't mention any actual offers.
2/22/10 Rivals article: Walker no longer knows about Pitt because they have filled up their scholarships. The article lists Oklahoma (only time Oklahoma was ever mentioned), Georgetown, Rutgers, and Seton Hall as offers.
2/25/10: Walker trims his list to Pitt, Georgetown, Seton Hall, Rutgers.
3/17/10: Seton Hall coach Bobby Gonzalez is fired.
3/25/10 Zagsblog: Walker claims he has offers from Minnesota, Pitt, Virginia, Marquette, Penn State, and Providence. Minnesota and Pitt are favorites.
3/29/10 Rivals article: Walker tells Ryan James that Seton Hall, Rutgers, and Minnesota are recruiting him the hardest.
--Minnesota quickly jumped to the top his list when they gave him a solid offer.
--I believe Tubby was the only coach to pay Walker an in-home visit and, other than Pitt, Minnesota was his only other visit.
--Seton Hall, Rutgers, and Minnesota "recruiting him the hardest" sounds like the only schools legitimately recruiting him.
--Walker's first list trimming included Rutgers, Seton Hall, and two teams that definitely didn't offer him (Pitt and Georgetown).
--Seton Hall's offer, if he indeed had one, likely vanished with Bobby Gonzalez's firing.
My reasoned inference: Walker had a lot of interest and perhaps even more offers early on, but teams were ultimately turned off some big red flags: weight, lack of athleticism, and awful conditioning. He's talented, but he needs to get in much better shape. Definitely a project.
