I think they should do what they can to hold on to Sauerbrun. It's only a slight exaggeration to say that he almost kept us in the game in the first half of the divisional round in San Diego. We were suffering slow death by poisonous field position and he kept booming the big ones out. And that's when not right at peak fitness either. If he can carry on like that, I see him being a big asset.
As for TE, I think that if Graham goes we assume we have just two. I like David Thomas a lot, but Garrett Mills doesn't even enter the equation until we see him on turf.
