Our WR corps for 2012 even without the obvious addition of a draftee looks pretty dangerous.
I fully expect Harbaugh and Roman to let Alex loose next season. They would not be upgrading the position with a guy like Moss if they wanted to remain as a run first, ground and pound type of team. Moss, if he wants to play, can be an absolute MONSTER; Manningham is a very versatile type of receiver, he can run the deep routes with good ability, has good hands, and can play the slot well.
You throw in Crabtree who has been improving each and every year in his career, and especially last year when he sort of became Alex's clutch WR to go to. Remember, we did not pass the ball very much last year. Being able to have 72 catches and almost 900 yards in just 14 games without preseason on a run first team is pretty damn good, IMHO.
And don't forget VERNON DAVIS. I can't understand why people don't consider him as a WR in our offense. VD is obviously the #1 option in this offense for 3 reasons:
1) Harbaugh likes to utilize tight ends in his offense. We saw that last year, especially in the playoffs.
2) Alex Smith prefers his tight ends as well. We've been seeing the Smith-to-Davis connection for 6 years now. It's a very lethal QB-Receiver connection.
3) Vernon is just that damn good player. We need to get him the ball as much as we can.
Vernon...Crabtree...Moss...Manningham...Gore...Hunter..
AND
OUR #1 DEFENSE.
