Bryans  Ball Sport variant

Close-ups of All Sport and Ball Sport backflashes

From these photographs it can clearly be seen that the Ball Sport is not simply an All Sport that somebody has modified by adding an extra 'B'!  The spacing of the letters and the overall shape is quite different.  Note the gaps between the letters on the Ball Sport.  Note also that the letters are in a different position with respect to the clouds and to the words 'I PLAY U'  below them.  In the bottom photo, the 'T' almost touches the stadium roof, wheareas in the top photo, extra clouds have been added to fill in the gaps.  Apart from the different names, the backflashes appear to be identical in all other respects (except for the colour of the fencers' socks!).
