Beanbags mark spots. Spots that need to be marked :
(1) live football goes OOB;
(2) runner with ball goes OOB;
(3) fumble downfield;
(4) where scrimmage kick ended;
(5) where scrimmage kick was touched by K;
(6) where free kick was touched by K in NZ.
Spots that do NOT need to be marked by beanbag :
(1) where free kick ended or pass intercepted - what you see on TV is for stats, fetching beanbag several yards downfield add a long ,unneeded journey;
(2) fumble in the backfield;
(3) where spot foul occurred - this should be marked by your flag, OK if moved to spot after initial toss.
I agree with you guys that it is tempting and acceptable to toss beanbag during any fumble -white hat's job to properly enforce. I listed some other uses earlier that I feel aid in game management that could be used.
When I returned to Maine in 1971, I had officiated in Connecticut for two years prior which was then a NCAA state. With me ,I brought a black hat with white piping (NFHS - sloid black), red and white flag (NFHS-solid red) and beanbag (NFHS used hats to mark spots). I quickly adopted the NFHS hat and flag, but kept using my beanbag. One of the officials was extremely interested in the beanbag and wanted to buy one. I later found out the interest : He wore a wig under his hat and was always worried that his wig, along with his hat would "mark the spot"
