Is it good in NFL FANTASY to draft rookies?

You should never take a rookie first round under any circumstance. NFL wideouts tend to blossom in their third season with few exceptions. Rookie QB's can be picked in the last couple rounds and will still most likely end up riding pine for you all season. Rooke running backs can have good first years but they will be there after the third round usually. Don't pick with your heart pick with your mind. You could probably get both of those guys in about the tenth round if the people you play with are any good. What I tend to do is if I pick in the top half of the first round I usually go for a stud back, if in the bottom half I like to get the best QB or WR available. Read up some more and take some time to prepare it will make a world of a difference. I would also advise doing some mock drafts on ESPN.com so you can get a feel of how the draft plays out. If you really want these two wideouts don't stretch for them but try to estimate when they will come off the board and grab them just before that at the last possible chance.
