I see Campbell and Colt, and I instantly think this is probably the best starter/back-up QB combo since Montana/Young
Seriously though. The highlight should definitely be Jason Campbell's performance. It was a brief performance but he really really looked good. Still, as LTF points out, don't sell short what Colt did out there (regardless of the talent surrounding him).
Most importantly, in both cases, they are getting their first full live game action since having major surgery and neither showed any side effects from it. That's the real positive.
