No Huddle / Hurry Up

[BKL]

How do you run the no-huddle or hurry up offense if you are actually doing the play calling in the game?

I noticed in the playbook there is a 2-minute drill. Do these plays actually run faster?

They seem to run faster in hurry up but I have no actual data to back that claim.
