Lift = Motion the player transfers into the ball with finger-LIFT
... so the more lift one has... the more revs one can put on his ball...
Staying behind the ball... mhh... how to explain this...
you can position your hand more under the ball or more to the side of the ball... with the term "Stay behind the ball!" people try to tell others not to come around the ball or even over the ball too much cause this usually kills ball reaction.
for me staying behind the ball means giving the ball more forward roll than side roll (NOT coming around or coming over the ball!) when I position my hand more to the side I give the ball more sideroll getting an earlier and more even reaction.
Once I stay behind the ball the ball has more forward roll with a more snappier reaciton and also a stronger backend reaction.
So with hand position during the release one can tune the balls reaction.
But I was often adviced to stay more behind the ball to get a more consistend reaction and also a stronger backend pop with better carry...
and that is what I understand by the term "stay behind the ball"....
