Before drafting players for your fantasy football team, you want to do your research. That includes analyzing players' stats, potentially watching their highlight tapes and dividing them into tiers so that you're completely ready to go when draft day arrives.
But with rookies, there are no NFL stats to analyze or NFL highlights to look at. These players have never stepped on to the field to play a game at the professional level. So no matter how much hype there is regarding a particular prospect, there's always a risk factor with drafting a first-year NFL player in fantasy.
