I liked Dave and Connor from the beginning and was glad to see them win. I think a lot of the criticism they received was unfair. Did Dave whine a bit too much after the still childless, green sequined couple U-Turned them? Sure. But, nearly every team that gets U-Turned gets at least somewhat angry about it. I think the fact that C&J and L&J took their side and formed the "accidental alliance" (hate that name) probaby resulted in a lot more of Dave's whining be aired. I also think they took it personally because they didn't realize the the Brenchels were gunning for the 1st place prize for the leg, rather than trying to eliminate them.
As for his achilles injury and his age being mentioned so often, both of those things were a big part of D&C's story line. I look at AR as sort of like a sporting event, and if a player is old, or hurt, or a cancer survivor, or whatever, it gets talked about a lot. Also, not all viewers watch every episode like most of us do, so many probably tuned in last night and in every other episode knowing anything about the racers. Does anyone get annoyed with the constant mentions that Caroline and Jennifer are country singers, that Jet and Cord are cowboys or that Herb and Nate are Globetrotters?
As for the "quality people" comment, I think it was as much a compliment to the other racers as it was an insult to the Brenchels. And, quite honestly, IMHO, the Brenechels are a lower quality of people than just about every other team in the race with the possible exception of Margie and Luke (really only Luke) and the Twinnies".
