Growing up, I remember hearing rumors of a retired Thurl Bailey (retired) vs. Ed Kehl matchup in the Sandy/Cottonwood area. Supposedly Kehl dunked on Bailey and said "welcome to church ball" as he ran back down the floor.
Luke Worthington vs. Joe Schobert (Cleveland Browns) was a good one in the Milwaukee area when we lived there. The synopsis on that match-up was Joe was really athletic and Luke was really tall.
There's gotta be some good stories out there (apocryphal, true, or both) out there that CBers have.
