What were the biggest surprises/disappointments this season?

What do you think the biggest surprises or disappointments were this season?  I think the biggest surprise was Dale Earnhardt Jr. leaving DEI and going to HMS has to be the biggest surprise.  To his fans, it can also be viewed as a disappointment since most Earnhardt fans don't like HMS.

Disappointments, I guess, can be viewed by who you like.  Both Kasey Kahne and Greg Biffle were expected to have good seasons after last year, but both struggled most of the season.  Dale Earnhardt Jr. and Ryan Newman also had some bad luck, mostly mechanical, at least on Jr.'s side, I know Newman had a few mechanical problems too.

And if you're a Toyota or Michael Waltrip fan, the first year with Toyota didn't work out as well as they all had hoped.  Waltrip missed a number of races as did other Toyota drivers, Dave Blaney and Brian Vickers did give some good showings though, so there is still hope there.
