Maynard is correct. If we're talking about the play where Dion got credited for a sack, Thomas had him well in hand on the play. Dion made an initial move which was unsuccessful, and so Dion completely disengaged his rush, pulled his hands down and went into spy mode. Weeden ran right into him and then Dion finsihed by grabbing Weeden's facemask. Technically a sack, but a bad play for Jordan and good pass pro by Thomas.
