question about rule in ncaa

[wtt0315]

so watching first punt in ucf game, the guy recieves the punt fumbles it backwards and out of end zone. why is this to the 20 and not where he touch it? if this is the case why wouldnt someone who is recieving punts and 1 always fumble it out of end zone to get it to 20.. Am i missing something here

[Dbldown11]

because he must not have had possesion of the ball. If he had possesion of the ball, then fumbled it out of the endzone it would have been a safety

[mtneer1212]

it was a muff -- which means there was no possession. It is a live ball, but there is no possession. In addition, a defense cannot advance a muffed punt.

dbldown and mtneer are correct...
