I've known about the Bud Grant for a few years, and just read he is still at it at age 90. This year he agreed to a bobblehead and had a bunch with autographs available at his sale:
The guy is God in Minnesota. Still lives in the same ranch style house from before he was the Vikings coach. Married his first only wife in 1950 (she died in 2009) and raised six kids.
I had a friend who played for the Vikings in the 60's said Grant was a prick as a coach, but to see how this guy continues to be embraced by Viking fans and the community is pretty touching.
