The first interception was a poorly underthrown ball; the ball went too high and hung up there. It's Boyd - if you're going to bomb it to him, then seriously bomb it and make him go make a play.
The second interception was simply Peterman staring down Boyd.
I was watching the game with an Iowa alum at an Iowa bar in Portland, OR (it's 1 of 2 here -- no Pitt bar, but as he said most Iowa alum are desperate to move out and far away). It was explained clearly to me after the first interception that that #14, and most of the DB's in general, are much more aware than in the past. His perfect example was the second one and the almost-third one. The entire bar was really frazzled by Boyd and couldn't understand how he kept getting open and never seemed to have a true double-team on him. They were also super impressed with how hard we hit.
