Why is it not a touchdown as soon as Campbell ''possesses'' the ball in the end zone and his knee hits the ground and the ball comes out?
Ah.....
Because (for whatever reason) the rule states you must "survive" the ground, Ie; the process of the
catch all the way TO and THROUGH the ground.....
That specific rule for "pass plays" / receivers - completely contradicts every other rule we know about football......
For example of a contradiction..... a running back who is tackled does not need to "survive" the process of going to the ground.... vivid example.... a running back is tackled from behind and his KNEES hit the ground, but he continues to fall forward and the ball comes out , before hitting the ground or not......
Doesn't matter.... as soon as his knees are down, the play is dead, even if the ball pops out before the tackle is technically finished....
Not the case with a "catch" on a pass play..... I don't know why and generally don't like the rule but I do understand it.
I guess on pass plays they want it "pretty" - regardless of the other rules that apply to every other rule of a ball carrier.
