We just hired our first nutrition expert to work exclusively with the program. There is a recent thread about it.
The S&C evidence is circumstantial: it looks like every player has gotten substantially bigger this off season, which is very different from the past.
Not every player has stayed skinny through the years, but it was extremely rare to see players absolutely transform their bodies during their time at Syracuse. We seem to have had several do it just this off-season. I am divining a change in focus caused by the change in head coach.
