That is a tought question. On opening day, JG. From week 4 on, HB. Holiday might be a good enough runner to confuse some defenses and all he needs is a step to go all the way. If he can throw a lick, he could surprise lot of people. Both he and HB are EEs so they have the off season, Spring practice and Fall practice to learn the offense. I realize that they will not learn the speed of the game until they face the real firing squad, but one can get a pretty good idea of how they are progressing by mid October.
