Who was a bigger disappointment last season. Shaun Alexander or Rudi Johnson?

As a fantasy player, it was Rudi Johnson for me because he had been so statistically consistent in previous 4 years and is a couple of years younger than Alexander. Alexander was a known gamble last year; big potential upside, but he was coming off a down year the previous season and had hit 30. He was a huge disappointment in 2006, but his 2007 stats weren't much different from '06.
