We can't recommend enough the importance of taking part in some mock fantasy football drafts before your real ones arrive. It's easy (just click here and join one), doesn't take much time and gives you the chance to make mistakes that don't count, while getting a feel for where players may land in your specific league size and format.
That latter part is key, because player value changes dramatically based on how many managers are in your league, the makeup of your rosters and your scoring system.
To that point, the value of quarterbacks rose in our recent 10-team, 2-QB mock when compared to our 10-team PPR, 10-team non-PPR and 12-team PPR drafts that rostered only one starting QB.
