Need Fantasy Football draft advice? Talk to CBS Sports on your Google Assistant to get insights on the best sleepers and to help decide between players. Just start with, "Hey Google, talk to CBS Sports."     

The point of tiers is to consolidate rankings of players into groups based on expectations. It's a necessary step in the process of getting ready for Draft Day -- and a secret of the pros.

But the most important person you take advice from on Draft Day is yourself. These tiers are mine, but I encourage you to shuffle them to your liking. At the very least, this is a good jumping-off point for you.

Once you tailor these to your specifications, you'll know where the strengths and weaknesses of each position are. Then on Draft Day, you'll know when you need to draft a player at a certain position or wait another round to get someone in a similar tier. It's a huge advantage to have over your unprepared opponents.
