PISCATAWAY -- The starting center on the Rutgers football team, Derrick Nelson, is officially listed on the roster at 295 pounds.

When he played varsity football at Georgetown nearly 50 years ago, Robert Barchi played the same position at 210 pounds.

It's why the university President marveled at what he saw Thursday as he stopped by for the start of the Rutgers football team's fourth practice of spring camp inside the Bubble.

"I told them that I played football and lacrosse almost 50 years ago for what was then a small-time program,'' Barchi told NJ Advance Media after addressing the players for seven minutes in a pre-practice huddle at midfield. "It bears absolutely no resemblance to this whatsoever. The only thing I recognize is lacrosse. It looks a little bit like what I did. But not this.''
