A lot of it is program stability and players on the roster. Tech will more than likely always be 30-40 win team under Bragga. A season like this though is combining that kind of stability under Bragga with an experienced roster where the experience (mostly Jrs and Srs) is made up of two special recruiting classes.
This is a special season for Tech that more than likely will not be able to be repeated until he gets another special core which may be 3-5 yrs. down the road.
In that time Vitello will more than likely recruit at a high level, get in more guys that fit his style of play, coach them up and the team will elevate to a much higher level.
