Hey, this is Coach Hoover. I have been running a series of articles on my site about the Defending the Flexbone. I have not revealed any of the identities of the guest writers as of yet, but I will provide a clue about tomorrow's (Saturday at 1:30 EST) guest writer.
You will probably be able to guess this certain individual by his affinity for a certain sports network.
...but if not, I provided another hint.
