According to this article from Neil Hayes, Charlie Weis would be interested in running the Bears offense should the position become vacant, despite six teams being interested in talking to Weis.
My prediction is that Weis ends up back in New England, but we'll see in a few weeks how this shakes down.
A source close to Charlie Weis confirmed that the former Notre Dame coach would be interested in the Bears' offensive coordinator position if it were to become available after this season.
