Yeah Jackson and Lynch were kind of flashes in the pan so it's not a guarantee they stay as top level talent. I like both, though.Lynch and Harvin are really important to you. You get 25 points a week from Rodgers, so that's nice.
And I feel similarly, but lower down, about both Harvin and Lloyd. Neither jumps to the front of your mind as huge impact WR, but I think both could be major studs this year. Harvin gets tons of touches, including carries and kick/punt returns. Lloyd had an amazing season under McDaniels with Denver, and now you add in Brady to the mix. He could just be a fringey WR#2, or he could be one of the better WR#1's.
I hate when I feel confident in my team, as it usually leads to embarrassing ruin. We'll see what happens. I've never gone into the season with a true stud QB in any of my fantasy leagues, so having Rodgers will be a big change (and I've got Brady and Stafford in my two other leagues).
