Rivera? He has 300 career saves and his post season record should count for something.
I think Schilling is a lock, no way he's not in. If he's not in then most of that list shouldn't make it either IMO. Regular season, post season, he's done it all.
Maddux is a big a lock as anyone listed there not named Bonds. I would also include Biggio and Palmeiro.
A couple of decent chance guys
McGriff - 500 HR is hard to pass on
Bernie Williams - He might need to get to 3000 hits and I'm not sure if he has the 4 years left in the tank.
Larkin - Dominating for a good chunk of years, still above average
Bagwell - His injured defense is hurting, but the bat might get him there
Frank Thomas - May need a couple more good seasons but his OBA is HoF.
Edgar Martinez - He's a DH so I wouldn't be upset if he got in or didn't but numbers wise he is a HoF guy.
