Perhaps it's ambitious to think that he should know all the NFL teams as a first round draft pick, but he should at least know that the organization paying his salary is in the AFC East. But before I throw stones it might be a good idea to provide the full rundown of the American Football Conference and the National Football Conference for the common man & woman (myself included, although I'm more of an exceptional woman).
Compliments of Holly Robinson Peete's tome Get Your Own Damn Beer I'm Watching the Game: A Woman's Guide to Loving Pro Football:
AFC East: Buffalo Bills, Miami Dolphins (that's you Tannehill), New England Patriots & NY Jets
AFC North: Baltimore Ravens, Cincinnati Bengals, Cleveland Browns & Pittsburgh Steelers
AFC South: Houston Texans, Indianapolis Colts, Jacksonville Jaguars & Tennessee Titans
AFC West: Denver Broncos, Kansas City Chiefs, Oakland Raiders, San Diego Chargers
NFC East: Dallas Cowboys, NY Giants, Philadelphia Eagles & Washington Redskins
NFC North: Chicago Bears, Detroit Lions, Green Bay Packers & Minnesota Vikings
NFC South: Atlanta Falcons, Carolina Panthers, New Orleans Saints & Tamp Bay Buccaneers
NFC West: Arizona Cardinals, St. Louis Rams, San Francisco 49ers & Seattle Seahawks
As a casual football enthusiast (or someone attempting to have sex with a football fan) it's not necessary to memorize the entire list above, but you should be able to at least name the conference that your favorite team is a part of and the other 3 teams in their conference. You may also score bonus points if you can name all 32 NFL teams. Another important fact to remember is that each year, the AFC Champion & NFC Champion play each other in the Superbowl. We will never see a Superbowl where the Steelers and the Ravens play each other no matter how awesome it would be.
Whew, that took an inordinate amount of brain power! If you want more information I would suggest you check out the Wikipedia for the full breakdown and some more in depth history (like the AFC didn't even exist until 1970 because there was a whole separate football league called the American Football League). Now I must rest up for the Steeler's game on Sunday.
