Spygate pre-emptive launch

HBO has Matt Walsh, the former New England Patroits video dude, on a special edition of "Real Sports" tonight (8 p.m. PDT). But before that, Patriots coach Bill Belichick has decided to jump on to CBS' Evening News (still with Katie Couric for some reason) and spill what he supposedly knows or doesn't know with Armen Keteyian. The two spoke earlier today in Boston. The piece runs sometime between 6:30 and 7 p.m.
