Technical or Intentional

[Nevadaref]

Additionally, when the whistle sounds is NOT the determining factor for live/dead ball in most cases. The ball becomes dead at the time that any violation, foul, held ball, etc. occurs. This action frequently precedes the sounding of the whistle by a second or two. Therefore, if the play described in the OP had been adjudged to be either a held ball or a traveling violation prior to the shove, then the shove would properly be treated as dead ball contact.
