Here are 10 key fantasy observations from Sunday's games, with analysis of the important trends and an eye toward next week and beyond.
Seattle surprises: Minus their two injured starting receivers, the Seattle passing game looked very shaky heading into Week 5. But Matt Hasselbeck stepped forth and was very efficient and proved he can get the ball regularly to secondary targets in a 37-31 victory at St. Louis. Hasselbeck threw for 316 yards and two TDs without being intercepted, and showed he can still be a quality fantasy passer without the missing Darrell Jackson and Bobby Engram. Joe Jurevicius caught nine passes for 137 yards and a TD and proved he can be a good fantasy option while Jackson is out. And if Engram continues to miss time as well, D.J. Hackett, who caught five passes for 43 yards but drew a flag on a long pattern to set up a score, will be worth a free agent add. Tight end Jerramy Stevens totaled 65 receiving yards and a TD, and should continue to be an important part of the Seattle air attack.
