So, maybe you're not an NFL GM (or maybe you are).

If you're an obsessive fantasy football player (guilty here), you know the tier system well. It's similar to what NFL teams use on draft day, to know when they're getting a player at a value, and when they can afford to wait around. Often, they're broken into position groups.

Our draft guru, Todd McShay, broke down the tier system for this year's draft, and placed players in several groups. Here's who landed where from the Big 12:

Tier 1 -- elite prospects

• Baylor quarterback Robert Griffin III was one of just five prospects.

Tier 2 --top 10 quality, but below elite

• OSU receiver Justin Blackmon was one of just two players.

Tier 3 -- good value in picks 10-20

• Texas A&M quarterback Ryan Tannehill was one of 12 players.

Tier 4 -- Late first-round value picks

• Baylor receiver Kendall Wright was one of 12 players.

Tier 5 -- Round 2 value picks

• Oklahoma State quarterback Brandon Weeden and Oklahoma linebacker Ronnell Lewis were two of 24 players.

Tier 6 -- Mid-to-late second round value

• none

Tier 7 -- Solid third-round picks

• Oklahoma State safety Markelle Martin, Iowa State guard Kelechi Osemele, and Oklahoma offensive tackle Donald Stephenson were three of 31 picks.
