I dispute that Moss was bad for TWO years in Oakland though. I read an interview with Norv Turner who coached the Raiders in 2005 and he said that he felt Moss played pretty well for him but got hurt midway through the season.
In fact here are Moss' stats thru game 4 in 2005:
19 receptions 466 yards 2 TDs
Not his 2007 stats to be be sure, but pretty respectable. Keep in mind his QB was Kerry Collins. Moss took a big hit in Game 4 and missed Game 5. The rest of the season, he wasn't that good but he did come back in Game 16 and had 7 catches for 116 yards and 2 TDs. He finished the year with 60 receptions, 1005 yards, 8 TDs.
No Moss was only bad in 2006 when the entire Raiders team was bad and I don't think he should shoulder the blame for an incredibly bad team.
