That line is Emmitt Smith's awesome argument for Michael Irvin's inclusion in the Pro Football Hall of Fame.
I've never been big on Hall of Fame discussions. It's fun to talk about, but I find it hard to believe that there's an absolute line that can be drawn that one could point to and say "everyone above this line is good enough, and everyone below this line is not."
But one interesting HOF argument centers around former Cowboys WR, current ESPN babbler, and constant source of amusement, Michael Irvin. Irvin's QB on the Dallas Super bowl teams, Troy Aikman, got in today. Emmitt Smith is a lock when he becomes eligible. Irvin, in his first year of eligibility, did not make the cut.
Also getting the call today along with Aikman were Harry Carson, John Madden, Warren Moon, Reggie White, and Rayfield Wright. Among getting left out with Irvin were L.C. Greenwood, Russ Grimm, Art Monk, Derrick Thomas, and Thurman Thomas.
