Incomplete or a fumble?

[Base]

I haven´t seen the situation, but as it was described, it can´t be incompleted pass under NCAA rules, because imcompleted can be only a forward pass (7-3-7-a; "incompleted" backward pass is a fumble) and forward pass is defined by points where ball left passer´s hand and where touched anything (2-19-2a) - not by that, what passer wanted to do (only exception to this is, when passer is tackled by opponent after forward movement of passer´s hand begins; 2-19-2-b)
