Or perhaps Hangartner helped Kalil out a lot? And if you're talking about the Panthers' moves, they let C Justin Hartwig go, and he only anchored the OL for the SB-winning Steelers. And then there was that gameplan in the divisional round of the playoffs that saw Delhomme throw the ball a lot, to the tune of 5 INT's, when the running game was their strength (and was a game in which Hangartner didn't play, BTW).
