What do you think are the minimum requirements to be in the HOF?

Zero for all of the above. There are dozens of players in the HOF who don't have Rings, MVP's, few if any All Star appearances or other awards. Career stats are variable depending on the type of player someone is. You can't put blanket minimums on any of these things or you will keep out deserving players. Membership in the HOF has to be decided on a case by case basis.
