It's the end of an era at Washington High School in Sioux Falls.  Head football coach Brian Hermanson announced Tuesday he is resigning effective immediately

Hermanson took over the Warrior program in 2005, coming over from Roosevelt, where he was the defensive coordinator.  He led the Warriors to a record six straight 11AA title games, including three victories in the last four.

In an e-mail to ESPN991's Brad Peterson, Hermanson said he wanted more time to focus on his son Matt, who plays football at the University of Montana:

Still plan on teaching and coaching track at Washington .  Just wanted to follow Matt his last two years.  Time to be dad for awhile.

Hermanson's Warriors have produced 22 Division I players. No replacement has been named.

Some of Hermanson's former players took to Twitter to react:

In addition, members of the sports community are also tweeting their thoughts on the coach's decision to resign.
