USC assistant Mack Garza resigns

USC secondary coach Willie Mack Garza has resigned, citing personal reasons, the school announced in a statement.

Obviously, the horrible timing -- two days before the season-opener versus Minnesota -- and vagueness here inspires a raised eyebrow and a, "Hmm."

The statement said the personal reasons are "unrelated to USC." That would suggest that this is more a Garza issue than a USC football issue.

Garza, 42, was with head coach Lane Kiffin at Tennessee and followed him to USC in 2010.

Here's the LA Times on the matter. It reports, "Former USC and NFL safety Sammy Knight is a graduate assistant on the staff and could oversee the secondary."

This shouldn't be a significant problem for the Minnesota game -- the game plan likely has been fully installed -- though it could complicate getting marching orders from defensive coordinator Monte Kiffin to his defensive backs.

It's also probably a good thing that USC has a veteran secondary, with three of four 2010 starters back, including preseason All-American safety T.J. McDonald.

Still, not the best way for a team to start off the season.
