You can fumble backwards all you want but the defense isn't going to just stand there and watch it. It's hard to get a first down moving the wrong direction. I've never seen a coach call an intentional backward fumble but I guess there's a first time for everything.
As to your vicinity of snapper question, you don't cite the complete rule reference but NFHS 7-3-Article 7 does not address planned loose ball plays. NFHS 7-3-8 does and states that ANY A player on his LOS may NOT advance a loose ball play in the vicinity of the snapper so I don't think you are discussing NFHS rules with us on the NFHS board.
Yes, I believe he is asking you an NCAA question because he quoted NCAA 7-1-7 Planned Loose Ball: "A Team A player may not advance a planned loose ball in the vicinity of the snapper."
My apologies for making this thread longer. Perhaps the mods can move it to the NCAA section so that he can get a better answer?
But let me try to give him a quick answer in the hopes it's useful to him:
Farooq, you ask exactly what is the "vicinity of a snapper". I don't believe that it's really defined.
I do know that the NCAA really wanted to get rid of the "fumblerooski" when they came up with this rule. They really didn't like that play.
So my personal guess is that since "vicinity" isn't really defined, that most officials would basically interpret that as being the tackle box.
Go ahead and ask this over in the NCAA section, instead of the NFHS section, and maybe you'll get a better answer.
