Not sure where you're getting this. He's not Jeff Heath in Dallas. I listen the local sports radio regularly and Sorensen is respected. Most callers and show host look at him as a competent part of the defense. The addition of Thornhill wasn't remarked upon as "now we can get rid of that Sorensen!" It was another good player added to the defense. He's very popular here. And Andy Reid is high on him, which is why he played most snaps, even when Thornhill was starting. He is a "wild card" that Spagnuolo brings in for multiple positions, plus as one of the fastest players on the team is a special teams stud.
