Agreed, that's an issue in general transitioning from college to the NFL let alone when you're from a smaller school or even a less competitive conference amongst the bigger schools. At the NFL level the vast majority of people can't just out athlete everyone else (Aaron Donald and Ndamakong Suh excluded), we saw that first hand on the offensive side with Reggie Bush to be honest. Could Reggie do it? Sure, at times. Could he do it every play like he did in college, absolutely not.
