1) Lock-down secondary. Seattle has the best secondary that the NFL has seen in a long, long time. They lock down receivers, even good receivers, with man to man, press coverage, which allows them to commit more players to the line of scrimmage. How do you see our receivers getting open? Which leads us to the biggest concern...
2) Kaepernick's inability to go through progressions. When your prime receiver(s) is locked up, the QB has to move through his progressions to other options. This has been an achilles heel of Kaepernick, who seems to panic when his first option is covered. I've been hoping they would establish some easy check-downs to backs, but that's not happening much. How do you think Kap will responds when he looks out and sees his first/second options covered?
3) The inability to audible. The crowd noise will likely prevent audibles from the line of scrimmage. Hand signals are tough to count on. The Seahawks seem to play off the noise by shifting though different defensive sets before the snap. How do you think the 49ers handle this?
4) Snap count. Related to the above. When you can't hear the QB's snap call, you have to be looking over at the center/QB. My lineman friends tell me that's a disadvantage because it shaves time off your release, when you are looking sideways. The only thing I've heard to counter it is timed snaps, but those are iffy.
5) Lack of fullback. Let's assume Tukuafu is out...I assume Dixon will have the starting fullback role. At 230, he's not the 293 pound load of Tuke…Do you think he will be enough?
Thanks for your insights, and GO NINERS.
