There’s always hope but all three of those guys have strong lists and it’s only the first week of June. Wouldn’t be surprised if the bigs we get aren’t even on our current list.
Sehic’s current offer list I believe is Iowa, New Mexico, Santa Clara, Princeton, Brown, Tulsa, Houston, Rice, and Davidson in addition to Lehigh. That is a pretty tough group to beat.
Nwankwo has offers from Tennessee, Seton Hall, Drexel, BC, Minnesota, a bunch of other mid majors and Lehigh.
Walker is probably the least heralded of the three at this point. He has several very solid mid major offers including UTEP and Davidson, but has yet to score a high major.
One other interesting name is Justin Greason. I can’t find any reported offers, but he has quite a bit of interest from both mid and high majors in the midwest. He has also said that he plans to visit Lehigh this summer in part because of the criminal justice program which is his preferred area of study. The fact that 1) he has no known offers at this point and 2) plans on coming to campus makes him someone to keep an eye on. That said, does Lehigh actually have a criminal justice program?
