reaction needed---- odd play situation:

[jwild1665]

I saw the first play described on the TV highlight show. The ball would not have been considered at rest with no player trying to gain control as the K player almost immediately went for the ball. The interesting situation was the K player just standing at the two with the ball and an R player standing in front of him, but no one moving. Looked like they were jawing a little bit. The covering official then kills it (forward progress stopped!). I think the official did it right all the way around.
As far as the second scenario, just because the players in the team bench area enter the field does not necessarily mean an illegal participation foul. The players who come on the field would have had to made an attempt to participate in the play. Otherwise it is a nonplayer foul that should be penalized as a dead ball foul (succeeding spot). See 9-6-3, 9-8-1-i, 10-4-4-c.
