Catch/No catch?

[VaHoops]

For NCAA, another thing to consider is that by definition, the ball being held (and subsequently thrown) by the "intercepting" DB is still a loose ball...

2-2-3-a
"A loose ball is a ball not in player possession during: 3. The interval after a legal forward pass is touched and before it becomes complete, incomplete or intercepted."

and

2-2-5-a
"A player 'gains posession' when he is firmly holding or controlling the ball while contacting the ground inbounds."

Until he returns to the ground, the ball is still loose, possession has not been established and a catch has not been completed. 2-19-1 tells us that "a pass continues to be a pass until it is caught or intercepted by a player or the ball becomes dead," so as strange as it may sound a ball firmly in the hands of an airborne player is still a pass (and it retains that status if he "throws" it).
