I don't think voters should make deserving players wait just for the sake of making them wait, but there are times when a logjam of WRs (C. Carter), DE/OLBs (R. Dent), RBs (Bettis) at one time and not everyone can get in immediately. I think in those cases you have to elect the best guys first, and if you have a Dent making it in before a Greene, or a Bettis making it in before a Martin, or an Irvin making it in before a Carter, then you can debate the first ballot stuff.
