1,200 yards would be great, but not likely. There have only been a handful of rookie WRs to hit 1,200 in the history of the NFL. I'm probably in the minority here (I usually am), but I don't expect a huge year from Watkins, for a number of reasons.
1) There is EJ. (I'm not bashing here) Having missed as much of the last season as he has, he is practically still a rookie. Assuming he steps it up, as we all hope he will, he still isn't going to be a polished vet. A rookie QB to a rookie WR doesn't equal 1,200 yards.
2) As talented as Watkins is, there will still be growing pains. I will admit, the only thing I have seen of Watkins is highlight reel material. That being said, we all know that defenses are a lot tougher in the NFL. Quite a few of Watkins' highlights included blown coverage that just would not have happened in the NFL.
3) If we see a lot of the three, or even four wide sets that some people are predicting (I hope we do), then let's hope that EJ spreads the ball around. A lot.
4) We have a talented stable of receivers. Assuming that EJ does step it up, I personally think that Woods is poised for a 1,000 yard season. I also think that if Mike Williams can keep his head on straight (Marrone obvious thinks he can), he can be a serious impact player. I understand why Lovie Smith dropped him, but he had some amazing plays with the Bucs. Add to that, CJ (who has great hands), and Chandler, who netted the most receiving yards last year.
Still-- no buyer's remorse.
