William Margraff

I am currently the Defensive Quality Control Coach for The University of Pennsylvania Football Team. I help coach the safeties alongside our defensive coordinator. I have also worked with the McDonogh School varsity football and baseball teams. I have worked with athletes of all ages across multiple sports. I am the son of Jim Margraff, the winningest football coach in Maryland state history, I grew up in the life of football coaching.

I played collegiate baseball at Rhodes College as both a catcher and short stop. At McDonogh School I was a three sport athlete playing football, basketball, and baseball. I was a first team all MIAA baseball selection two times in my career, and was awarded the prestigious John Amedori award. I was a two year captain for the McDonogh baseball team. Due to injury, I ended my baseball career early at Rhodes College, and earned a spot as a walk on for the mens lacrosse team. Thus, I was a member of two different collegiate sports teams.

Each session will be tailored to the skill development of the individual athlete. The position focus will be dependent on the player. We will begin with a base understanding of posture and necessary strength and movement mechanics and then build to more advanced techniques as the player progresses. This will include multiple football positions from both skill to line and either side of the ball.
