Should L.C. Greenwood be in the Pro Football Hall of Fame.?

I asked a similar question earlier execept it was for a different player. I was wondering do you think L.C. Greenwood should be in the Hall of Fame. He is a 6 time Pro Bowler and was named to the 1970s all decade team. Was part of the Steel Curtain defense that helped the Steelers win 4 Super Bowls in the 1970s. He had 73.5 sacks in his career (unoffically) and had 14 fumble recoveries. Hall of Famer or not?
