The best solution I heard was to have the Ump look to see if the offense is coming to the line w/o a huddle, then if so, he goes to the old spot. If they are in the huddle then he goes to the new spot. This requires him to think and make a split second desicion and that might be too much.
Oh and give him a small helmet w/o a mask and some pads.

I guess will see how it works out tonight.

What...... the double reverses hitting the ump?

OOps.....sorry ref. But you sprang me for a nice run. Thanks. lol

Just as long as they don't disrupt the game like they did in preseason
