timing issue...

[MJT]

I think I may have found some things to put this discussion at rest.
3-4-3b says "snap" if B is awarded new series - did not happen.
3-5-7c says officials TO following a change in team possession - we did have that. After penalty consideration, B not given new series, so don't have to start on snap as stated in 3-4-3b. Tackle was IB, so that would indicate RFP.
Casebook 3.4.3D says "With 3rd-10: (a) A1 fumbles the ball and B recovers, or (b) A1's pass is intercepted by B. When will the clock start? RULING: Since a change of possession has occured in both (a) and (b) and B is awarded a new series of downs, the clock will start on the snap.
This "and" in the casebook was a big one in my changing sides to the RFP. That "and" would not have to be in there, but with it being there indicates to me that for it to start on the snap, both the COP "and" new series for B must occur.
I now say RFP.
It is discussions like this that make me love these boards. The arguing back and forth gets you in the book and keeps us fresh. Thanks!!
