On a different note regarding USC quarterback Matt Leinart, we're told that Leinart recently was "Punk'd" by Ashton Kutcher and his show of the same name on MTV. Though the details are sketchy at this point, what we're hearing about the prank calls to mind the misadventures of actor Hugh Grant several years back. Leinart agreed to permit the segment to be aired when MTV likewise agreed to wait until after the April 29 draft to air it. We hear that the "Punk'ng" is scheduled to be shown on May 1. But since the incident is phony, why would Leinart's people want MTV to wait to broadcast the thing? In our view, Team Leinart realizes that there are concerns as to whether Matt has a sufficient passion for pro football -- and as to whether Leinart might decide to pull a Jim Brown after a couple of seasons playing with a supporting cast that can't dominate its way to a 16-0 record. For the younger readers out there who might be confused by what seems to be a derogatory reference to a Hall of Fame running back, Brown walked away from the NFL at the peak of his career to become a movie star. In Leinart's case, there's a fear that a decision to ditch football could come long before he rings up the kind of numbers that would secure him a spot in Canton.
