Flag Spot, and FP questions

[jjrye22]

2 questions fro a tournament I worked last weekend.

1. LJ on kickoff. For the first time ever I had a K player run out of bounds then back in a few steps later (no contact from a R player). I knew it was a foul, but had no idea how I should throw it... I am on the goal line, he came back in somewhere around the 50. Is it ok to just flag it? Shouldn't it be specific to the spot that he came in?
As it was, I froze up and didn't flag it (confusion, disbelief). The kick ended up out of bounds on the other side as well - but I would like to know how to deal with this correctly next time.


2. (Also as LJ). RB runs in the middle of the field. Gets tackled, and the tackler throws himself backwards and twists... Kind of hard to describe, but the runner landed on his back ON the tackler. As they hit the ground, the tackler lets go, and the runner bounces sideways onto his feet again - starts running again after regaining his orientation.
The U blows the play dead, and from my view it seems like an IW. I tell him, and he says no - forward progress was stopped. I think he was just covering himself (we are all from different states at a youth tournament and didn't know each other), but wanted to see what you all say. I know it is a 'had to see it' play, but maybe you can give me some input as to wheather the player is down if he doesn't touch the ground and kept moving?

Thanks for the info,

James
