One guy being better than another guy is just football. Doesn't mean the other guy isn't coming along just fine.
I've said since the day they drafted him that Harris has a chance to become a special player with his off the charts speed and athleticism. If he's "earned it" already, he's on a really fast upward trajectory. The guy has played very little football compared to the others, so he has tons of room for development. Maybe he's just one of those guys that can rather easily translate instruction to actually doing it. Not saying that he's ready for a big role.... but you never know about guys like this. Nobody thought Kittle was going to set the league on fire as 4th round pick.
