Some coaches would rather unplug their headsets than play a true freshman, while others don't hesitate to throw newbies into the fire. Of course, most of the time it's not a matter of choice but available talent.
That's why I tracked how many true freshmen played in Week 1 for each Big East team. Sometimes this gives you a good idea of where teams are and sometimes it says how talented the freshmen are. Two true frosh started in Week 1: Marquis Spruill at outside linebacker for Syracuse, and Preston Brown at middle linebacker for Louisville.
Here's a list of which straight-out-of-high-school players played the opener, according to the official participation reports (note that many of them played on special teams, not necessarily their listed position):
Cincinnati (1): Adrian Witty, DB
Connecticut (1): Leon Kinnard, WR/QB
Pittsburgh (2): K'Waun Williams, DB; Aaron Donald, DL
