Yep. He had give out some envelopes to staff members, then he pulled the gun out of the envelope he had. I remember him saying something like, "stay back, this could hurt someone.." just before he put the gun in his mouth and shot himself.
Stuffing the box to stop Alexander is big mistake. He has had a lot of success turning broken plays into long TD runs. If he breaks through a hole at the line when the Bills are in an 8 or 9 man front, he's gone.
