Unfortunately, the predraft camp is notoriously bad for big men, and its mostly big men that are intriguing for the C's there.
If anyone is able to watch it, and get a report on guys like Devon Hardin and Trent Plaisted.
The other guys who could be interesting would be Shan Foster, JR Giddens, and Keith Brumbaugh (someone I am intrigued by, based on what I have read...but have never seen).
