Kraft didn't make it to the HOF either. I didn't remember that Gibbs took 3 years to get in (first year eligible 1994, ends up getting in 1996). I really can't get annoyed or care much at Bill or Bob not getting in now, the Hall entry is, once you're in, you're in. They'll get in. That's all that will ultimately matter. It isn't a huge deal to not get in, first ballot - I think it's more of a story than anything else.
The fact that Gibbs and Monk didn't get in on their first ballot makes it all "meh" to me. I think Bill should have gotten in first ballot, but then I think Gibbs and Monk should have been locks as well. So meh.
