not sure what you are getting at here... wr is the same as qb on running plays?
Absolutely not. WR's are expected to block on running plays, a QB does nothing but hand the ball off, rarely are they asked to block players and if so more often than not it's more like simply get in their way then block them.
the qb runs all the plays running or passing for the offense.
Every player on the offense runs the play, not just the QB. The QB CALLS the play. The QB still calls the play in the huddle on a wildcat. Granted he doesn't call the snap on the play, see my comments below.
henne isn't very experienced doing this, so he should take as many reps as possible within the live game to get this experience. on running plays an experienced qb will get everyone lined up, read/interpret the defensive formation, recognize certain players that may adjust blocking or technique, snap the ball with a certain cadence to get timing of the play correct, etc... it isn't simply a "mindless" snap and handoff role.
And yet none of that "develops" a QB in my humble opinion. I'm pretty sure that Pat White, Chad Pennington or Tyler Thigpen can do all those things as well as Henne can. Developing a QB is done on pass plays where he has to go through his read of the defense and progressions. That's simply NOT done on a run play regardless of whether he lines up wide or takes the snap.
