They seem to always draft a team of RBs and WRs and QBs and neglect to grab a K or a DEF. They grab all these big names and seem to miss the point of having reserve slots (so you can have a full squad to start every week.) Whatever, the nfl.com mock drafts are just a timekiller to me to be honest.
It really depends on the league you are in. My league the QB is #1 priority followed by RB then WR/TE. Kickers and Defense can be dropped and added each week with little effect. Keep in mind our league has two starting QB's each week.
The most fun I've had playing fantasy football was in my IDP league. Any retard can predict Calvin Johnson will catch more balls than Jerome Simpson, takes a lot more knowledge to get on top of injuries and stats in defense only leagues.
