Filed under: College Sports, High SchoolScroll halfway down the athletics page of the web site for Cretin-Derham Hall, a Catholic high school in St. Paul, Minn., that is home to the nation's most highly-touted football recruit. There you will come upon the following note of felicitation: "Congratulations to the following student-athletes that have signed NCAA national letters of intent to play collegiate athletics: Seantrel Henderson-Football-University of Southern California" If only. While the 6-8, 330-pound offensive tackle did appear live on national television last Wednesday to announce that he would attend USC, he is still yet to sign his national letter of intent. Henderson, whose father Sean is heavily invested in his son's choice (the family discussed plans to move to Los Angeles just last week), will wait at least until after the NCAA infractions hearings that USC will be subjected to between February 19-21 in Tempe, Arizona, before scrolling his signature on a letter of intent.
