Back in the '90s, I remember players being told in tournaments that they needed to personally retrieve their Disc when stuck into the side of the basket cage before it falls to the ground in order for it to count as being holed out. I witnessed on more than one occasion a player sprinting to the basket to do just that.
(...and I have an ace that occurred in that fashion where I sprinted the 267' to retrieve it! My Banshee stuck right into the side of the cage in the shape of a taco's tortilla shell. I count it; it was during a casual round, though.)
