The next four days could go a long way of determing former Yale quarterback Patrick Witt's NFL prospects.

Witt, one of the rare Ivy Leaguers to be invited to the NFL combine, is one of 19 quarterbacks taking part in the festivities which for quarterbacks began today with a pre-examination including x-rays, orientation and interviews. Tomorrow there will be measurements (height, weight, wing span, side of hands and whatever else they can come up with), interviews with the media and psychological testing. On Sunday quarterbacks will go through the drills for the NFL scouts.
