That's about as expected. No worries. Fair and equal playing time based on performance thus far. Though, to be honest, it does seem to suggest pitting Delhomme against Weinke, when that's not necessarily the case.
Davis' shoulder might not be perfect. Either way, he's probably the most important offensive player we have right now - putting him in too long, especially against his old team, could cost us. We know what Davis can do, he's not competing against anyone. Get him two series to make sure everyone's on the same page, then bring in Hicks and Brown rotated.
