that we can a) gawk over the beauty of his Sheik play and b) pick apart the different parts of the combo.
Well, if we want to pick it apart I will say the technical aspects are fun. Its simply a shame its not guaranteed.
0:36 - Utilt -> Ftilt
Fox is on the ground long enough it looks like that he could have shielded.
The following Ftilt -> Ftilt looks like Fox once again could have shielded in between these two things.
The following Filt -> Dtilt situation same thing. Another possible shield opportunity for someone.
Everything else in between there I cannot easily tell since Fox is launching high enough and is staying on the ground for less time after that.
However, with the finale 0:47 if you look closely Fox CPU jumps into the Bouncing Fish. You can tell because you can see the little circle prop that appears anytime someone 2nd jumps. If Fox simply fell down and did not jump Bouncing Fish would have missed and Fox would get a free rain back to the stage.
