Call me Crazy but it would appear that Coach Paul Johnson can hold his own on this list, and throw in the College APR mandate that some on the list did not have to follow and the NCAA probation thru June 13, 2017 and the fact that some recruits have not worked out like Travis Custis and Myles Autry. Along with the fact that high school players who considers college nothing more than "the NFL minor league" are looking for the easiest route to that ultimate goal, the NFL, are not going to wrestle with the academic rigors at GT. Coach Paul Johnson has been great for GT.
I do understand that people want a 9-10 win season every year, however we are not a football factory and whoever coaches at Georgia Tech will have to be willing to coach and recruit at a disavantage to other football factories in the Southeast. It is what it is!!
