Nice video and analysis, but the big animation programs all contain simulation packages, which will calculate precisely this, it may even be easier to simulate the collision than to animate by hand. ( And what really put me off in the video is the use of time lapse in the repeated kicks, precisely at the moment where one could hide a cut.)

On the other hand a NFL level kicker is roughly 50% for 50+ yard field goals. [1] Therefore the 5 50 yard field goals should be possible for an NFL kicker in something like 2^5/2=16 tries. ( Similar for the 60, 50 etc sequence, using again the stats,

1/3.* (24./47)* (96./141.)* (120./136)* (119/121.) = .1

it should require something like 10 tries. ( Assuming a probability of 1/3. for the 60 yrd.) So I think the video is genuine, but only because I wonder why anyone would spoil an impressive video by just one special effects shot.) To really convince me, one would need to calculate the kick of the second ball, since this is the moment where animation and reality have to match.
