The Tommie Harris int was just a good play. And a bit of luck. I asume you saw it, being our incognito ursine and all. That was just a 4 yard dumb off on a screen. Stafford invited the rush really well, but Tommie Harris fell down, then got up, and found himself right in front of that ball.
I must say that I've been really surprised by how these young guys are performating at the WR position. I'm still not convinced that moving Hester was a good idea, but Knox and company are playing really well.
