Here is a pretty comprehensive preview of Lehigh/Xavier from a Xavier fan site. Also of note is that Xavier will likely be without Myles Davis and JP Macura (suspended indefinitely). Davis averaged 10ppg last year and Macura averaged 9 as the Big East Sixth Man of the Year.
Xavier will still have a ton of talent but if one or both does not play it definitely will affect their depth and experience.
There would be more to talk about if there were some level of news coming out of practice, either through the athletics department or local media.
