Bruce Smith - All-time sacks leader, right?
Shannon Sharpe - Arguably the best TE ever, if you go purely by passing stats and Super Bowls (and don't factor in blocking as a prerequisite for "greatest").
"Bullet" Bob Hayes - Changed the way the game was played. I think this is finally his year. They don't go against the Veterans Committee's wishes twice on the same guy, do they? A crime if he's not voted in.
Ralph Wilson - Owner for 50 years should do the trick.
Rod Woodson - I could see him getting voted down, but he shouldn't.

I can't believe Paul Tagliabue didn't get in last year, but I'm guessing they might turn him down again. He was the commish when the league gained complete dominance over American sports. Guess Pete Rozelle gets all the credit for setting the table, I guess. He had a pretty long term, so I can't think it's a longevity thing.
