When it comes to fantasy football, not all NFL draft prospects are noteworthy, regardless of talent.
For example, USC left tackle Matt Kalil is regarded as the consensus No. 1 offensive line prospect. But in fantasy, the addition of one elite lineman will not substantially transform his team's offensive performance. A running back may gain more yards running to his side, but good defenses adjust to that accordingly.
Likewise, one defensive player prospect can play at an elite level on his NFL team—such as Arizona's Patrick Peterson—yet not move the needle much on his team's overall defensive performance.
While important pieces to the puzzle, such talented players are not as important to fantasy football owners as offensive skill players.
The following are the top 15 NFL draft prospects that fantasy football owners should keep an eye on for 2012. Their projected impact will further shake out once we know their NFL destination, which I will cover in a future article after the draft.
