Over the years I have seen what seems like almost every catching DVD out there.
My favorites include:
Tom Griffin - Carson-Newman
Turtle Thomas - when at LSU
Ron Davini - (for HS kids)
Dave Weaver (for the young kids)
I also like the online videos from Ian Berksdale at Louisville and Joe Wilkins.
My favorite of all of them is the one I have put together for our HS kids. Has a combination of everyting I have learned from all the videos, handouts, etc., I have ever collected.
